does the sperm or egg determine gender
Sperm contains either an X(female) chromosome or a Y(male) chromosome, whereas the egg contains only an X(female) chromosome. Neither the egg nor the sperm can be said to have asex.. The combination of an X-bearing sperm with the (X-bearing) egg produces a female baby. The combination of a Y-bearing sperm with the (X-bearing) egg produces a male baby. It might seem that the man (sperm) that determines the sex of the baby, but this assumes that the egg is passive, accepting the first sperm to arrive at the egg.
