$XO$ type of sex chromosomes determine male sex in grasshopper.

Vedclass · Answer

(B) : $XO$ type of sex chromosomes determine male sex in grasshoppers. This type of sex determination comes under $XX-XO$ type. Its common examples are cockroaches,grasshoppers,and bugs. The female has two homomorphic sex chromosomes $(XX)$ and is homogametic. It produces similar eggs,each with $X$-chromosome. The male has one chromosome only and is heterogametic. It produces $2$ types of sperms: gynosperms with $X$ and androsperms without $X$. Fertilization of an egg by $X$-bearing sperm yields female offspring and by no-$X$ sperm yields male offspring. The chromosomal constitution is represented as $AA + XX$ (female) and $AA + XO$ (male).

Column-$I$ (Mechanism of Sex Determination)	Column-$II$ (Example)
$P$. $XO$ type	$I$. Grasshopper
$Q$. Haplo-diploid mechanism	$II$. Drosophila
$R$. $XY$ type	$III$. Honey bee
