If I remember correctly from junior year chemistry, during fertilization, the egg has an X chromosome either way (because females are XX), and the sperm will either have an X or a Y (because men are XY).
So, a sperm cell made from a woman's stem cell would pretty much have to be X, correct? A stem cell can become pretty much anything, but I don't think it can become something that simply does not exist in its host's genetic code.
That is correct. After all, sperm can have an X in it, so I don't really see why a lack of Y would be a problem here. The Y chromosome doesn't do much other than control development of male reproductive organs and that's pretty much irrelevant in this scenario.
I guess this means that lesbian couples can only have girls. As a species we have eliminated the need for men!
Or did the scientists discover a way to get a sperm that has either X or Y from the woman's stem cell?
I kind of doubt it, but idk.
I amuse myself.

I would suspect it could help with increasing diversity in severely endangered species as well *NM*

I hadn't thought of that, but that is a good use of this technology as well

Really cool. Although, I'm confused. Does the female stem-cell sperm have a Y chromosome?

I think it would have to be an X
