Which of the following is the genotypic ratio of Mendel's monohybrid cross?

In a cross,$45$ tall and $15$ dwarf plants are produced. The genotype of the parents is .....

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 $Gg$?

How many different types of gametes will be produced by a plant with the genotype $AABbCC$?

When Mendel crossed a true-breeding white-flowered strain of peas with a true-breeding red-flowered strain,the individuals in the $F_2$ generation represented:

In one of the hybridisation experiments,a homozygous dominant parent and a homozygous recessive parent are crossed for a trait. (Plant shows Mendelian inheritance pattern)
