The genotypic ratio of a monohybrid cross will be

What is the proportion of dwarf and tall plants in the $F_{2}$-generation of Mendel's experiment?

What was the phenotypic ratio of the progeny obtained in the $F_2$ generation in Mendel's monohybrid cross experiment?

In $Drosophila$, the allele for a normal grey body colour $G$ is dominant to ebony body $g$. The following table summarises the results of several crosses:

$S.No$	Cross	Result
$I.$ Strain $1 \times gg$	All wild type
$II.$ Strain $2 \times gg$	$1$ wild type $: 1$ ebony
$III.$ Strain $3 \times gg$	All ebony
$IV.$ Strain $4 \times Gg$	$3$ wild type $: 1$ ebony

Which strains both have the genotype $Gg$?

If a dwarf plant is treated with gibberellin,it becomes tall. If this plant is now crossed with a pure tall plant,what will be the progeny of the $F_1$ generation?

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