Vedclass · Answer

(B) Female heterogamety is a mechanism of sex determination where the female produces two different types of gametes. In birds,sex determination is of the $ZW-ZZ$ type,where females are $ZW$ (heterogametic) and males are $ZZ$ (homogametic). In honey bees,sex determination is based on the number of sets of chromosomes (haplo-diploidy). Females are diploid $(2n = 32)$ and males are haploid $(n = 16)$. This is not considered female heterogamety in the traditional sense of sex chromosomes. Therefore,birds exhibit female heterogamety. The correct option is $B$.

In which of the following organisms is female heterogamety observed?
