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

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

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 $Drosophila$, 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 two different alleles of a gene are present in an individual,this condition is known as:

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