$A$ cross between one tall plant and one dwarf plant resulted in offspring having tall plants. What would be the genotype of offsprings?

What will be the phenotypic ratio of the offspring produced from the cross $Tt \times tt$?

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 $Gg$?

When a homozygous red-flowered pea plant is crossed with a white-flowered plant, what color will be produced in the $F_1$ generation?

In a plant,the genotype of the $F_1$ generation is $AABbCC$. Upon self-pollination of this plant,the phenotypic ratio in the $F_2$ generation will be:

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