My daughter had a bone marrow transplant when she was 16. The donor was male. She is now 30 and is pregnant. She just had some blood work done, and the lab called to say that the blood sample they sent in was male, not female! My daughter is now worried about the baby looking like the donor instead of her, and/or having medical issues. Does she need to worry about this?

I was born male, and received a bone marrow transplant from my sister to treat leukemia. A bone marrow aspiration a few years back concluded I had female DNA in my marrow, while a normal blood test would show male. 1) By this fusion am I a chimera? 2) Would I have an extra sex chromosome? And finally, I recently came out as trans (M to F). In my case, am I genetically trans? Or getting my hopes up?
