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 sounds like you’re asking how mosaic DNA works. Consider a set of fraternal twins (the kind with different DNA).
As embryos they develop to the point where their cells start to differentiate. One of the first things to differentiate is skin cells from bone, muscle and neural. If both twins recombine, the types of cells have changed but haven’t formed any organs yet. They can form one person out of two sets of DNA for different organs.
