Vedclass · Answer

(C) In humans,the sex of the baby is determined by the sex chromosomes. Females are homogametic,possessing $XX$ chromosomes,and produce only one type of gamete (ovum) containing an $X$ chromosome. Males are heterogametic,possessing $XY$ chromosomes,and produce two types of sperms: $50\%$ containing an $X$ chromosome and $50\%$ containing a $Y$ chromosome. When an $X$-carrying sperm fertilizes the ovum,the zygote becomes $XX$ (female). When a $Y$-carrying sperm fertilizes the ovum,the zygote becomes $XY$ (male). Therefore,the sex of the baby is determined by the type of sperm provided by the father.

Why is it scientifically correct to say that the sex of the baby is determined by the father and not by the mother?
