At the time of fertilization

Vedclass · Answer

(A) The sex of a human baby is determined at the time of fertilization. In humans,the female produces gametes with $22 + X$ chromosomes,while the male produces two types of sperm: $22 + X$ and $22 + Y$. When a sperm carrying an $X$ chromosome fertilizes the ovum,the resulting zygote is $44 + XX$ (female). When a sperm carrying a $Y$ chromosome fertilizes the ovum,the resulting zygote is $44 + XY$ (male). Since this genetic combination is established the moment the sperm fuses with the egg,the sex is determined at fertilization.
