I'm intrigued... can you elaborate more on this or provide links for

info???

I'm afraid not. The course I did on reproductive biology predates the web
by a couple of decades, so they didn't give us URLs :-(. I can't even
remember exact details of the genetic basis.

This is from memory and also 1970's genetics. We have come a long way
with both evolutionary genetics and developmental biology since then, and
what I was taught at the time may have been since disproven.
