Using a Punnett square, work out the distribution of phenotypic features in the first filial generation after a cross between a homozygous female and a heterozygous male for a single locus.
Using a Punnett square, work out the distribution of phenotypic features in the first filial generation after a cross between a homozygous female and a heterozygous male for a single locus.
In guinea pigs, heterozygous male with black coat colour $(Bb)$ is crossed with the female having white coat colour $(bb)$. The male will produce two types of gametes, $\mathrm{B}$ and $\mathrm{b}$, while the female will produce only one kind of gamete, $r$. The genotypic and phenotypic ratio in the progenies of $\mathrm{F}_{1}$ generation will be same i.e., $1: 1$. (figure)
