Question

state one genetically different feature between sperms and eggs of humans. What is its consequence?

Answer 1

In humans, sperms have XY sex chromosomes while females have XX. The consequence of this is that sperm play a role in deciding the sex of child. As females are XX they can only contribute X but sperms are XY so they can either contribute X or Y to the offspring. If sperm contributes X then the offspring will be female and if contributes Y then the offspring would be a male.
