just an addition to my post before my post confuses anyone. I am a lesbian, my wife is a lesbian. we use a donor for our children, the same donor, and we use UVF. to put it bluntly the donor does his thing in a cup, the female side of things is taken through a surgery process, then in a lab they are joined together. the cells that formed my daughter and son came from the same egg. when one egg forms the same child, the resulting children are called identical twins. why because it was the same egg. not two different eggs. due to a lab accident my daughters side of the egg was damaged. this caused my daughters side of the one egg to develop problems that her identical twin did not. one of those problems was when she normally was supposed to grow a male appendage, the reproductive side of her development split into two, (male and female otherwise called hermaphroditism) instead of just one a male or female child. so now my daughter has bone marrow that is producing blood alternating from mate to female to male to female (otherwise known as mosaic blood production)... it is my wife and I have have chosen to hold her body at female rather than have it constantly conflicting causing her to have mental issues. Some day my child may decide for her/his self whether they want gender reassignment surgery that will enable him/ her to be just male or just female.

my point sometimes identical twins do not mean the child is going to look and be the same as its twin. it just means they came from the same egg, not two separate eggs being fertilized. According to all the doctors, scientists and specialists that my daughter has seen she is and always will be an identical twin with her brother, and if the lab accident hadnt happened I would have either two girls or two boys.
