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)
From a single ear of corn, a farmer planted $200$ kernels which produced $140$ tall and $40$ dwarf plants. The genotype of these offsprings are most likely
When a gene exists in more than one form, the different forms are called
Some pure black mice were mistakenly mixed with hybrid black mice. The quickest way to discover whether one individual black mouse is pure is
