aussie-cg - this is interesting, but I'm not quite sure I understand - well, I'm sure I DON'T understand.
I thought I was following what you were saying, until you said "this means the calf is more likely to reflect the mother in traits found on the sex chromasomes if it is a male". I was expecting you to say FEMALE. So, can you explain it in even MORE laymen's terms????? :lol:
Haha. Ok. Heres a picture. (Pictures are easy right? )
A female's sex genes are XX and a males are XY so if the child is a male it has recieved the Y chromosome from Dad and the X from Mum (seeing as males pass on the Y chromosome.) And as you can see from the picture, the Y chromosome is a sorry looking guy who is missing a huge chunk of the genes contained on the X chromosome. So a bull calf gets its X chromosome from Mum and Y from Dad, but because the Y chromosome is missing so much info, the genes on the X chromosome he got from Mum are most likely to be expressed. Does that make more sense? I get carried away sometimes, sorry
