(B) In humans,the sex determination mechanism is of the $XX-XY$ type.- The female is homogametic,producing ova with $22 + X$ chromosomes.- The male is heterogametic,producing sperms with either $22 + X$ or $22 + Y$ chromosomes.- When a sperm carrying an $X$ chromosome fertilizes an ovum $(X)$,the resulting zygote has $XX$ chromosomes,which develops into a female child.- When a sperm carrying a $Y$ chromosome fertilizes an ovum $(X)$,the resulting zygote has $XY$ chromosomes,which develops into a male child.- Therefore,the combination of two $X$ chromosomes (one from the mother and one from the father) results in a female child.
