(A) In humans,sex determination is of the $XX-XY$ type. Females are homogametic,producing gametes with $22 + X$ chromosomes. Males are heterogametic,producing gametes with either $22 + X$ or $22 + Y$ chromosomes. When a sperm carrying an $X$ chromosome $(22 + X)$ fertilizes an egg $(22 + X)$,the resulting zygote has a chromosomal composition of $44 + XX$,which develops into a female. Therefore,the correct composition for a female-destined zygote is $44 + XX$.

In humans,the chromosomal composition of a female-destined zygote is:
