(C) In humans,the sex determination is based on the $XY$ chromosome system.Females are homogametic,meaning they possess two $X$ chromosomes $(XX)$. During oogenesis,all ova produced contain only one type of sex chromosome,which is the $X$ chromosome.Therefore,females produce only one type of ovum $(22 + X)$.Males are heterogametic,meaning they possess $XY$ chromosomes. During spermatogenesis,two types of sperms are produced: $50\%$ of sperms contain the $X$ chromosome $(22 + X)$ and $50\%$ of sperms contain the $Y$ chromosome $(22 + Y)$.Thus,males produce two types of sperms.

In terms of chromosomes,females produce $.......$ type of ova,while males produce $.......$ types of sperms.
