Vedclass · Answer

(D) In humans,sex determination is based on the $XY$ type of sex chromosomes. Females are homogametic,producing gametes with $22 + X$ chromosomes. Males are heterogametic,producing two types of sperms: $50\%$ with $22 + X$ and $50\%$ with $22 + Y$ chromosomes. If a sperm carrying the $X$ chromosome fertilizes the ovum,the zygote develops into a female $(XX)$. If a sperm carrying the $Y$ chromosome fertilizes the ovum,the zygote develops into a male $(XY)$. Therefore,the sex of the offspring is determined by the sex chromosome contributed by the father.
