In a Mendelian monohybrid cross,the phenotypic ratio in the $F_2$ generation is $3:1$. How many types of gametes are formed in the $F_1$ generation?

If a cross is made between $AA$ and $aa$,the nature of ${F_1}$ progeny will be

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 $Gg$?

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

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

If a cross between two individuals produces offspring with $50\;\%$ dominant character $(A)$ and $50\;\%$ recessive character $(a),$ then the genotypes of the parents are:
