Zoology - Principles of Inheritance and Variation Question with Solution | TestHub

Genotype of male $=\mathrm{AaBbX}{\mathrm{X}}^{\mathrm{h}}\mathrm{Y}$ Number of gametes $=2^n$ Where $\mathrm{n}=$ no. of heterozygous alleles (genes A, B, sex chromosome) Thus, Number of gametes $=(2{)}^3=8$ The gametes produced wil be $={\mathrm{abX}}^{\mathrm{h}}$, $abY,{\mathrm{ABX}}^{\mathrm{h}},\mathrm{aBY},\mathrm{aBX}{}^{\mathrm{h}},\mathrm{AbY},\mathrm{ABY}$ and ${\mathrm{AbX}}^{\mathrm{h}}$. Hence, number of sperm carrying $\mathrm{abh}=1/8$.
