(A) In humans,the sex of the child is determined by the sex chromosomes inherited from the parents.Human males have $XY$ sex chromosomes,while human females have $XX$ sex chromosomes.During gametogenesis,males produce two types of sperms: $50\%$ carrying the $X$ chromosome and $50\%$ carrying the $Y$ chromosome.Females produce only one type of ovum,which always carries the $X$ chromosome.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 male gamete (sperm) that fertilizes the egg.
