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 provides an X or Y chromosome; the mother always provides an X chromosome. Therefore, the sex of the child is determined by the chromosome of the individual sperm that fertilizes the egg.Male offspring carry XY chromosomes; female offspring carry XX chromosomes.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).
