(B) In many insects,the mechanism of sex determination is of the $XO$ type. In this type,females have two $X$-chromosomes $(XX)$,while males have only one $X$-chromosome $(XO)$. During gametogenesis in females,all eggs produced contain an autosome $(A)$ and one $X$-chromosome $(A + X)$. During spermatogenesis in males,two types of sperms are produced: $50$% of the sperms contain an autosome and an $X$-chromosome $(A + X)$,while the other $50$% contain only an autosome $(A + O)$. Therefore,it is observed that some of the sperms bear the $X$-chromosome.
