(A) In birds,the female is heterogametic $(ZW)$ and the male is homogametic $(ZZ)$.In humans,males are heterogametic $(XY)$ and females are homogametic $(XX)$.In Drosophila,males are heterogametic $(XY)$ and females are homogametic $(XX)$.In honey bees,sex determination is based on the number of sets of chromosomes (haplodiploidy),where males are haploid and females are diploid.Therefore,the heterogametic male condition ($XY$ or $XO$) does not occur in birds.
