Moron here: Are XY females sterile or is it possible for them to pass on the Y, along with a male partner Y gene to give the baby YY genes? Or is this combination non-viable and wont develop?
Mothers always pass the X chromosome due to how the egg works from what I remember. The sperm determines whether you get x or y for the second part.
There is a rare event where you can have multiple sex chromosomes, like XYY, but the X is always present (at least for humans). Considering the genes in an X chromosome are vital to life, even if we could artificially create YY, it would probably end up nonviable
There’s a bunch of them, but one more common example is Androgen Insensitivity Syndrome.
It’s also possible to have a non-functional SRY (XY but female), or to be XX with an SRY translocation (XX but male).
Biology is complicated: pretty much anyone who says it only happens one way or is really simple is wrong.
“Yeah… SRY, but sex and gender are not a binary.”
