Without going on a google hunt.....
The male contributes an xy (if the offspring is to be male)
and the female xx
So couldn't the x and the y come from a male?
ie the human female has a chromosone pair xx and xx
whereas the male has xx and xy
Not unless it's a clone.
It's the y from the male that makes the child male. The X comes from the mother, it's in the egg cell.
