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

In a monohybrid cross experiment,the genotypic ratio of the progeny in the $F_2$ generation is ....

Describe Mendel's Monohybrid experiment.

In a cross between $AaBB$ and $aaBB$,what will be the ratio of the genotypes $AaBB$ and $aaBB$ in the progeny?

In a plant,black seed color $(BB / Bb)$ is dominant over white seed color $(bb)$. In order to find out the genotype of the black seed plant,with which of the following genotype will you cross it?

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 $Gg$?
