No, That's not how any of this works... The DNA comes from the egg, the uterus (aka womb) is just an incubation chamber. Would only have the sister's DNA if it was an ovary transplant. | ||||||||

> Would only have the sister's DNA if it was an ovary transplant. Fun fact: fetal cells transmit back to the mother and can be spotted in virtually every organ afterwards - it's called "Fetomaternal cell microchimerism" [1]. It's not a far stretch to assume the transfer works also the other way around and you can detect maternal DNA in the fetus/child, but I'm not aware if there has been research around that.
