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

The proportion of plants that were dwarf and tall,respectively,in the $F_2$-generation of Mendel's experiment was?

What is the phenotypic and genotypic ratio in a monohybrid test cross?

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 $Gg$?

What is the percentage of the recessive phenotype in a cross between $pp$ and $Pp$,where $P$ is dominant and $p$ is recessive (in $, \%$)?
