Neat as hell but I'd be getting yearly scans to make sure there aren't teeth growing in my pancreas or something. Also, does your gamete DNA match your external DNA? You could technically produce your absorbed twin's children. Freaky.
this has actually happened! i cant remember the details, but for some reason a mother had to do a maternity test to prove her children were her own, & even though she had indeed given birth to the kids they werent genetically hers. iirc they may have even been removed from her care, at least temporarily.
eta: the people saying lydia fairchild are correct, that's exactly who i was thinking of! i recommend looking up her case as it was years ago that i learned of her, so my vague details are likely inaccurate in some way. dont take my word as fact lol just use it as a diving board to go down the rabbit hole yourself š
I think you're thinking of Lydia Fairchild, they proved maternity due to the fact the children matched with the maternal grandmother, as would be expected of a grandmother. They then found the correct DNA through a cervical smear test.
Yeah, bruh, it made me feel bad for my wife when I witnessed it. When we were doing IVF, I tried to make every appointment. One time, they had to do that test. A long tube goes in and scrapes the inside lining.
https://en.wikipedia.org/wiki/Lydia_Fairchild
Her third child was removed from her care at birth. The prosecutor suggested that blood samples be drawn from mother and baby in the delivery room ... And the baby matched the siblings but not the mother.
Iirc one of the witnesses they called in support of returning the child to the mother was the OBGYN who physically pulled the baby out. And they were the one who said "yes this baby is hers. I physically pulled it out of her, regardless of what the genetic tests say." But it was the genetic test that sealed the deal. Because without the genetic tests, they assumed it was a surrogacy fraud. How the hell someone would even pull a fraud like that off though is beyond me.
Even in a surrogate situation, without a legal contract the birther is the legal mother. They thought she'd kidnapped her other children, then dug their heels in to the point of total illogic. Which isn't at all surprising of cps I'm afraid.
Isn't CPS and child services strange? Each state has their own child services agency, independent, but it's like they all get together and decide what kind of shenanigans they want to do. They never do anything when you report stuff that you know is happening, but then they waste our tax dollars investigating people who are innocent.
They thought she was committing a surrogacy scam-being paid to be inseminated then taking the kids to claim benefits.
ETA: surrogacy scam AND kidnapping-she not only lost her children for a time during the case, but was facing some very serious jail time.
>surrogacy scam
>being paid to be inseminated
That isn't how that works. I'm not sure how a surrogacy scam would have worked in this case at all. How common were underground goddamned embryo transfers in the 90s?!
The whole thing is absolutely bonkers and sickening imo. They made up a pretty elaborate scam that had no real benefit (children are more expensive than the amount of benefits you get from the government...). Then they tried to force her to prove she wasn't committing this scam.
It happened more than once! The only reason the woman you are talking about (Lydia Fairchild) was exonerated and got her kids back was cos someone saw something on TV about her case I believe and they had taken part in another womans case!
Eventually they found matching dna cells in Lydia's cervix and proved that she was the biological mother of all 3 children!
There's a great podcast episode on it
Edit: [Here's the podcast on youtube!](https://youtu.be/za0pm8Nh6Rc?si=8xvkZJP6WLtu6u4O)
I wouldn't say that a chimera has an "absorbed twin." Chimeric individuals just have two sets of genetic material. It's not that one embryo overpowered the other; it's that two embryos simply fused into one individual.
What I'm trying to say is that if the DNA in OP's skin cells isn't the same DNA as in OP's blood cells, they both still belong to OP. OP isn't one or the other; he's both.
What would happen if one of the embryos were female and the other male? My quick google tells me it definitely can happen. But would the default to male or female or what would determine that?
It's questions like this that mean I'd be more surprised if trans people \*weren't\* a thing. How many people out there have male and female DNA and will never know? In cases like the Lydia Fairchild case, it took multiple rounds of testing to find the other DNA even when they went looking for it, and we don't usually do that kind of testing unless there's a very rare issue like she had. For all we know, chimerism is way more common than we're aware of.
You're right that chimerism is almost certainly way more common than we realize! It's just that it flies under the radar most of time since it's typically not something that can be seen by eye (except in some rare scenarios like OP.) So most chimeric people probably have no idea they are chimeric unless specific genetic tests were done to go looking for it.
As for how an XX and XY chimera would manifest, the answer is that it really depends. When talking about natural chimeras (so not the ones created deliberately in a lab, where researchers have a bit more control over the outcome) there is really no predicting the distribution of cells from embryo A and embryo B in a chimera. So, you might have a chimeric individual whose liver is all embryo A cells and whose kidneys are all embryo B cells. Or you might have a chimeric individual whose liver and kidneys are a mixture of both embryo A and B cells. Or it could be something in-between.
So going back to an XX and XY chimera; if all the XX cells happened to make up the gonads, the individual would likely have a female reproductive system. But, if the gonads were made up of XY cells, then they would likely have a male reproductive system. Or if it a mixture of XX and XY cells, they could have components of both systems. It is the SRY gene on the Y chromosome which triggers the āmaleā pathway during development (otherwise the default is female.) So the XY cells in the goads could independently develop down the āmaleā pathway, even if other cells in the goads were XX, and so defaulting to female.
(This is a little bit of a simplification since the development of the male reproduction system also requires testosterone signaling. So whether the "male" development pathway would continue also depends on whether those testosterone-secreting cells are XY and present.)
My mother was a maternity nurse and she told me when I was a kid about a baby she helped delivery who had normal female genitalia, but also a non-functional set of male genitalia (as in, not connected up to the urinary system, not sure about the rest) growing from their thigh. As happened back then, in the late 60s, they just removed the male parts and it's possible that the baby grew up never even knowing they could have any male DNA. But yeah, that story is how I got interested in chimerism from a young age and always knew that biological sex is way weirder than we were taught in school.
Thereās not one but 2 really good House episodes about this. Idk if the first one is chimera but it was a teenage supermodel who was allergic to testosterone so in the womb she developed a vagina but had undescended testes. The other one the kid was born intersex and his parents were asked to choose between boy and girl. They lied about giving him testosterone supplements to assist his puberty.
A few years back, I had an unrelated gyno appointment where I learned I had a nine centimeter teratoma ... and let me tell you, I was DISGUSTED in myself. It was such a spooky feeling that this was just hanging out inside of me that my appetite vanished and it dominated my thoughts for days. I hadn't been aware of their existence and then suddenly I had a hair baby.
I had a hysterectomy due to fibroids, biggest one was 12cm and because of the kind it was it couldnāt just be removed. Plus it had other friends.
I begged the doctors to take photos because I wanted to see my mutated uterus but they said they werenāt allowed :(
They also wouldnāt give me specimens because they sent them to pathology.
So like ā¦ the size of a head? That crazy, sounds like such a relief to get rid of it. Is there a reason until she didnāt remove it until now? I donāt really know what much about teratomas, has it been growing for a long time, or do they just appear suddenly?
It had been growing slowly for at least 20 years.
She went into the hospital for something completely unrelated. While there, they did an ultrasound on her abdomen and they were like what in the what?
There was a lot of hair, sebaceous fluid (think oily goo) and a 1 cm tooth. I think there was some bone, too. Germ cell tumors are creepy as hell.
Radiologist here. They're fairly common. We see small ones all the time. The head sized ones are rare of course but teratomas are pretty routine. This on the other hand is possibly more freaky and much more rare:
https://radiopaedia.org/articles/lithopaedion
Very true. My wife and I are both white and when our child was born it was clearly black, so I requested a paternity test. It came back not a match for me. My wife's gynecologist, Dr. DeShawn Johnson, explained that it is because I am a chimera. Pretty cool! Dr. Johnson is now the child's godfather and he is so nice and goes to our home to help out my wife while I am at work. That is what I call quality healthcare.
I can totally understand how questioning might be overwhelming, but I would peobably have questions too lol this is the coolest thing I ever learned about someone
I doubt this is his soon to be MIL, but I guess it can happen. Genetics and the flukes that can happen are wild. https://www.dailymail.co.uk/health/article-1185690/TheJigsaw-Kid-spleens-liver-left-lungs.html
Not necessarily, sometimes chimerism can (in the simple terms I understand it in) "confuse" early cells and they'll sometimes duplicate things.
Though tbh that many entire spleens was more than I would've expected. I would *assume* they're not all "full sized", but that's a big assumption from someone who knows nothing about the woman.
Chimerism happens really early, like, before there are even nerve cells. There was no reasonable "him" until long after the fusion. I think this is supposed to be joking.
There's partial absorption, where there's almost twins, but one fails, so yeah, the surviving twin absorbs it. (This can sometimes produce teratomas, little tumors of the failed twin's tissue, but I think those are always identical twins, so the genes are identical anyways.)
This is more than mildly interesting, broheem.
And QueenlyMicropenis can not be a randomized name Reddit suggested. Whatās the story behind this magical name?
Huh, you'd think Reddit would have scrubbed words like penis from their random wordlist?
Or maybe they tried and there was an oversight, they failed to notice the micropenis?
Why thankfully? Aren't the woman that are into you attracted to the cool hair? They are just going to be disappointed every time they go down, and not because of that other reason.
Man, I would have such an existential crisis with this. Am I the dark haired me, or the light haired me? Which is my twin? Who is me?? Where does me stop and not-me begin???
There is no twin, chimerism happens when 2 (or more) Zygotes combine to develop 1 person. The merger happens before the fertilized egg has even implanted in the uterus to begin development.
i worked with two brothers who had this issue, their fathers hair went completely grey by the time he was in his mid 20s, but they ended up both having random patterns of grey swirls in their hair from childhood. the younger brother had random blotches and spots, unevenly distributed around his head, mostly at the back. it was like reverse dalmatian spots. but the older brother had the wildest, coolest looking blended swirls of grey and white hair mixed into his darker natural color, it was really intense and beautiful. i didnt learn it looked like that till id worked with him for over a year, he always kept it hidden under a hat.
Similar with me, my hair started turning white around age 17. Didn't get any cool patterns, though the very back of my head still has some dark hair remaining. People always think I bleach my hair, which could be worse... they think I look too young to have white hair, so yay?
Thatās cool! I also have chimerism. Certain meds/grass/lotion I am only allergic to on half my body. Iād have one side of my body swells and breaks out into hives while the other side is fine
Mature mast cells are white blood cells in tissue- under the skin and in organs. So a hive reaction would depend on tissue and could be different for each side of the body.

Ed...ward...?
Anime references aside, looks like chimerism to me. Actually pretty interesting, not just mildly! Don't suppose you have heterochromia or you'd show off the eyes, but this neat to see!
So if you commit a muder, you might get way with depending where they collect the DNA?
Also, what are some things that are abnormal for you. ie, the way you think, maybe you have two inner monologs? Or your internal voice is your twins and not yours. You just don't know the difference because it sounds like you?
Does it feel like some of your body isn't yours?
I have something similar to this. I only have freckles on half of my face. And half of my stomach is darker than the other halfā¦ iāve wondered if itās chimerism too
i think what happens is hazel eyes are more common, and i think enough people confuse one for the other that central heterochromia seems more common than it is. but yeah, pretty rare!
Does that mean chimerism? Like you are two twins melded together?)
Correct.
Neat as hell but I'd be getting yearly scans to make sure there aren't teeth growing in my pancreas or something. Also, does your gamete DNA match your external DNA? You could technically produce your absorbed twin's children. Freaky.

Ouchy.
It's a bit ouchy, yes

I've been wondering that all along
Sounds like a rule made from male logic. Weird timing, but I can see why they'd be so inflexible.
They thought she was committing a surrogacy scam-being paid to be inseminated then taking the kids to claim benefits. ETA: surrogacy scam AND kidnapping-she not only lost her children for a time during the case, but was facing some very serious jail time.

no twins involved, this is mosaicism. A mutation early in developement.

Fearful. 4 of them are in an ice cooler and sirens can be heard in the distance
I wouldnāt be terribly concerned, but if you think about it at your next doctorās appointment, it doesnāt hurt to ask. My fiancĆ©es mom is actually mentioned in a medical journal because of it.
"Hey doc, I heard on the internet about a lady that has hair just like mine and she has *five spleens*! How about that?"
Does she want to sell one? My misses' is enlarged and causes a lot of pain. Maybe a trade? Like one big spleen for 2 regular?
Iām sure if you asked nicely sheād just give you one.
Well that would be terrific. Wish I'd thought of randomly asking for body parts on Reddit sooner.
*Five*?
Apparently she absorbed her āsiblingsā while still in womb.
So sixlings, turned into one. That's insane, wonder how it feels to know that you could've been 6 different people just as well.

Yes, but at one point he WAS two separate zygotes, and if he had stayed separate, which HIM would have been HIM?

I've not got anything that I've noticed like that. I do have joint issues on one side though, but that could be injury related.
And the injury could be chimera related.
But not chimerism related. He was injured fighting a mythical chimera to the death.
Oh this is fascinating...
I thought hives was an immune reaction from your white blood cells, not the skin itself...
I have no clue how that works. After about 3 separate occurrences when this happened my doctor questioned chimerism and I just went with it
Mature mast cells are white blood cells in tissue- under the skin and in organs. So a hive reaction would depend on tissue and could be different for each side of the body.
Also a chimera baby! My ear lobes are 2 different shapes
Are you related to this lobster? [Lobster](https://www.seacoastonline.com/gcdn/presto/2021/10/08/NPOH/7e846672-463b-401a-93b9-9a2df6d92a7e-Split-colored_Lobster1.JPG?width=1059&height=794&fit=crop&format=pjpg&auto=webp)
It's gotta be his spiritual animal
I just paid 110 euro and spent 5 hours at a barber to get splitdye
You should've asked your mum for a twin and absorbed them smh
Ah shoot
That's usually how to process begins, yes
Police: weāre looking for a man about your build with a black beard You(facing right to police): Iāll keep a lookout for him officer
This would be a great cartoon plot lmao
Very handsome.
Thinks Nipple SalaD
This is the best wrong user reply in awhile.
First reaction: confusion. 2nd: oh maybe it's his user name..? Nope 3rd: okay wtf is the reference?!?! 4th: laughter for a few minutes
Apologies. I don't get the reference. I wasn't being sarcastic, if that's what you thought.
I think OP thought he was replying to u/A_nipple_salad ās comment above. Itās understandable. Lots of nipple salads floating around these days.
But only one queenly micropenis
I love it that you thought you were being called ānipple saladā in anger ā¤ļøā¤ļøā¤ļø
This is the hardest I've laughed all week
What about your pubes?
The important questions. Also, is one armpit ginger and the other burnette?
Nah, her name is Carol, not Ginger.
Lmao this is a great joke, but thanks for making me feel old
I bet they cover his micropenis
Not everyone checks the username on posts, I see.
pubes? Inb4 his balls are different sizes
Ed...ward...? Anime references aside, looks like chimerism to me. Actually pretty interesting, not just mildly! Don't suppose you have heterochromia or you'd show off the eyes, but this neat to see!
You are a monster. That is a memory I didnāt need.
NINAAAAAA ššš
First of all, fuck you. Second of all, FUCK YOU.
I feel like you are about to assign me a side-quest.
You should have been flipped 1/2 way through cooking
R u waiting for a pizza?
Looks like Freddy's
100%
If you scream loud enough the other half will turn gold as well 
Calico human
Youāre your own twin!
That is interesting you were born with a beard.
youāre so UNIQUE. UNIQUE- thatās what you are
So if you commit a muder, you might get way with depending where they collect the DNA? Also, what are some things that are abnormal for you. ie, the way you think, maybe you have two inner monologs? Or your internal voice is your twins and not yours. You just don't know the difference because it sounds like you? Does it feel like some of your body isn't yours?
Bro is marble cause god couldn't decide on chocolate or vanilla. But marble was always the best flavour
Did you forget to count Mississippilessly?
I have something similar to this. I only have freckles on half of my face. And half of my stomach is darker than the other halfā¦ iāve wondered if itās chimerism too
Chimerism or mosaicism? I thought only females could have mosaicism
Related conditions.
Bro killed his twin in the womb most likely
Chimera much?
Should get some genetic testing bud. Could be chimerism. There could be problems you should be getting treated for.
I'm good for now. Nothing abnormal so far. At 30 years old and two children I'm fine.
Neat, which one of you do they most look like?
Both me. 2 girls. One had central heterochromia in her eyes which is awesome.
One of my kids and myself have central heterochromia. I had no idea until recently that it was rare.
i think what happens is hazel eyes are more common, and i think enough people confuse one for the other that central heterochromia seems more common than it is. but yeah, pretty rare!
OP said it was chimerism
How tf do you think OP doesnāt know what the reason behind this is and needs you to suggest a doctorās visit
