Vedclass · Answer

(A) The correct answer is $A$. In humans,the female has a pair of $X$ chromosomes ($XX$ - homogametic composition),and the male has $XY$ chromosomes (heterogametic composition).During fertilization,the fusion of an egg (containing an $X$ chromosome) with a sperm (containing an $X$ chromosome) results in a zygote with two $X$ chromosomes $(XX)$.This $XX$ chromosomal constitution in the zygotic cell leads to the development of a normal human female child.

Which one of the following conditions of the zygotic cell would lead to the birth of a normal human female child?
