The X and Y chromosomes, also known as the sex chromosomes, determine the biological sex of an individual: females inherit an X chromosome from the father for a XX genotype, while males inherit a Y chromosome from the father for a XY genotype (mothers only pass on X chromosomes).
The father's genetic contribution determines the sex of the baby. Women have XX chromosomes, men have XY (this is part of the definition of female and male). The male provides â¦ either X or Y to the woman's X. So if the man donates an X, the baby is XX and thus female.If he donates a Y, the baby is XY and thus male.n humans, it is the sperm which determines the sex of the child. The presence of a Y chromosome in the zygote is what determines that the child will be male. Only the fathe â¦ r has a Y chromosome (XY).
