Vedclass · Answer

(A) In bugs and cockroaches,sex determination occurs via the $XX-XO$ type mechanism.In this system,females possess two $X$ chromosomes $(XX)$,while males possess only one $X$ chromosome and lack the homologous partner,denoted as $XO$. During gametogenesis,the female produces gametes that all contain an $X$ chromosome $(A+X)$. The male produces two types of gametes: half containing an $X$ chromosome $(A+X)$ and half lacking a sex chromosome $(A+O)$.When these gametes fuse,the resulting offspring are either $AA+XX$ (female) or $AA+XO$ (male),maintaining a $1:1$ sex ratio.
