Can the DNA remain in a girl after an abortion?

Answered Oct 25

Yes. It is called fetal microchimerism.

Material from the foetus can pass through the placenta, into the mother. This can result in ongoing cell lines which are based on that foetus, with a genome based on both parents, so different to the mother’s own genome. These cell lines can persist for the rest of the woman’s life.

No, you cannot grow a new foetus from these cells.
