Vedclass · Answer

(B) In humans,the sex of the child is determined by the sex chromosomes present in the sperm. Females have $XX$ chromosomes,and males have $XY$ chromosomes. During fertilization,the mother always contributes an $X$ chromosome through the ovum. The father can contribute either an $X$ or a $Y$ chromosome through the sperm. If the sperm carrying the $X$ chromosome fertilizes the egg,the child will be female $(XX)$. If the sperm carrying the $Y$ chromosome fertilizes the egg,the child will be male $(XY)$. Therefore,the father is responsible for determining the sex of the child.
