Vedclass · Answer

(B) In humans,the sex of the child is determined by the father's sperm. Females produce eggs that contain only the $X$ chromosome. Males produce two types of sperms: those carrying the $X$ chromosome and those carrying the $Y$ chromosome. If a sperm carrying the $Y$ chromosome fertilizes the egg,the resulting zygote will have $XY$ chromosomes,which develops into a male child. If a sperm carrying the $X$ chromosome fertilizes the egg,the resulting zygote will have $XX$ chromosomes,which develops into a female child.
