I thought this story was interesting. For those not reading the article, ovarian tissie was taken from one identical twin sister and transplanted into the other twin who was infertile. The recipient twin had a baby a year later. Apparently this has been done sucessfully a few times with identical twin sisters and once with a woman’s own ovarian tissue that had been frozen. This made me wonder if the subsequent children of each sister would actually be half-siblings of their cousins?
As I understand it, identical twins have identical DNA, or at least it cannot be distinguished by any method currently available. So would that mean that normally cousins of identical twin mothers would actually be genetically half-siblings?
The other interesting thing to me was that the ovary recipient sister went through menopause at 14!
