If a heterozygous red-flowered plant is crossed with its pure-breeding red-flowered parent,the offspring will show:

Normal maize has starchy seeds which remain smooth when dry. $A$ mutant form has sugary seeds which go crinkled when dry. When a mutant was crossed with a normal plant,an $F_1$ was produced which had smooth seeds. What would be the relative ratios of the different seed types,if the $F_1$ was allowed to self-pollinate?

In the case of inheritance of one gene,the phenotypic ratio of $3:1$ can be explained on the basis of which of the following?

$A$ cross was made between a pure tall and a pure dwarf pea plant to produce progeny. The progeny was self-pollinated. Find the ratio of the resulting true-breeding tall and dwarf plants.

If a dwarf pea plant was treated with Gibberellic acid,it grew as tall as a pure tall pea plant. If this treated plant is crossed with a pure tall plant,then the phenotypic ratio of the offspring is likely to 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 $Gg$?
