What is the gender of YY?

The Y chromosome contains a “male-determining gene,” the SRY gene, that causes testes to form in the embryo and results in development of external and internal male genitalia. If there is a mutation in the SRY gene, the embryo will develop female genitalia despite having XY chromosomes.

Does the Y chromosome change?

The Y chromosome is a puny bit of DNA that has only a few genes. And the genes it does have mostly deal with being male. … It does change a little from generation to generation and it even picks up a bit of mom’s DNA along the way. It just doesn’t change as much as most of our other chromosomes.
