Vedclass · Answer

(C) The sex of a human child is determined at the time of fertilization. In humans, the female produces only one type of gamete (ovum) containing the $22 + X$ chromosome constitution. The male produces two types of sperms: $50\%$ containing $22 + X$ and $50\%$ containing $22 + Y$. 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 genetic sex is established at the moment of fertilization.
