In many species, sex determination is genetic: males and females have different alleles or even differ. Sex determination. A baby's sex is determined at the time of conception. When the baby is conceived, a chromosome from the sperm cell, either X or Y, fuses with the X chromosome in the egg cell, determining whether the baby will be female (XX) or male (XY) genes that specify their sexual morphology.
