I know I just posted but how come a person can have different DNA in their womb than their mouth yet get a transplant and their body whacks out?? (Not talking abt a baby lol I think it’s called chimeraism??)
In: Biology
It helps that while the cells are different, that are from the same parents so they are less likely to be rejected. Like getting a kidney transplant from your sibling. But even then it can lead to autoimmune disorders.
There’s also a bit of survivorship bias here. If the cells aren’t compatible the person wouldn’t survive to be an adult.
