Answer:
In human beings, the females are homozygous and have 2 X chromosomes, i.e., XX, and the males are heterozygous and have one X and one Y Chromosome, ie, XY. The offspring which is produced receives one X chromosome from the mother while it is the father's chromosome which determines the sex of a child. If the child receives one X chromosome...then zygote formed is XX which means the child is girl. If the child receives one Y Chromosome, then the zygote formed is XY, which means the child is boy. In this way sex of a child is determined in human beings.
