Vedclass · Accepted Answer

In grasshoppers,the male sex is determined by the $XO$ type of sex chromosomes.

Vedclass · Answer

(B) In grasshoppers,sex determination is of the $XO$ type. The males possess only one $X$ chromosome besides the autosomes,whereas females have a pair of $X$ chromosomes. Thus,the presence of a single $X$ chromosome determines the male sex,while the presence of two $X$ chromosomes determines the female sex. Option $A$ is incorrect because in birds,males are homogametic $(ZZ)$ and females are heterogametic $(ZW)$. Option $C$ is incorrect because $XO$ in humans results in Turner syndrome,which is a female with underdeveloped ovaries. Option $D$ is incorrect because in Drosophila,$XX$ chromosomes produce females,not males.
