Vedclass · Answer

(D) In humans, the diploid number of chromosomes is $46$ ($23$ pairs). These consist of $22$ pairs of autosomes and $1$ pair of sex chromosomes ($XX$ in females and $XY$ in males). During spermatogenesis, meiosis occurs, resulting in the formation of haploid sperms. Each sperm receives $22$ autosomes and one sex chromosome. Since the male genotype is $XY$, $50\%$ of the sperms will contain $22$ autosomes and an $X$ chromosome, while the other $50\%$ will contain $22$ autosomes and a $Y$ chromosome. Therefore, a sperm contains either an $X$ or a $Y$ chromosome.
