The percentage of heterozygous individuals obtained in $F_2$ generation from selfing the plants with genotype $Rr$ would be

When a heterozygous tall plant is crossed with a homozygous dwarf plant,what will be the proportion of dwarf progeny in the next generation (in $\%$)?

In humans,blue eye color is recessive to brown eye color. If a blue-eyed woman marries a brown-eyed man whose mother had blue eyes,what will be the expected eye color of their children?

The genotypic ratio of a monohybrid cross in $F_{2}$-generation is

In the case of inheritance of one gene,the phenotypic ratio of $3:1$ can be explained on the basis of which of the following?

$A$ cross was made between a pure tall and a pure dwarf pea plant to produce progeny. The progeny was self-pollinated. Find the ratio of the resulting true-breeding tall and dwarf plants.
