Ans: After going through heterozygous meaning it is very simple that a person has two copies of a gene (one inherited from one parent, and the other from the other parent). The X and Y chromosomes, which play a role in gender differentiation, are known as sex chromosomes. One from each parent, women inherit two X chromosomes. As a result, a female can be homozygous or heterozygous for a given X chromosomal characteristic.
