(C) The observed ratio of $73.97\%$ tall and $26.03\%$ dwarf is approximately $3:1$.According to Mendel's law of segregation,a phenotypic ratio of $3:1$ in the $F_2$ generation is obtained when both parents are heterozygous (hybrid) for the trait.Cross: $Tt \times Tt \rightarrow TT, Tt, Tt, tt$.Genotypes: $1$ $TT$ (pure tall),$2$ $Tt$ (hybrid tall),$1$ $tt$ (pure dwarf).Phenotypes: $3$ tall $(75\%)$ and $1$ dwarf $(25\%)$,which matches the experimental data.

When experimenting with the factor of tallness in $Pisum$ $sativum$,Mendel obtained the results $73.97\%$ tall and $26.03\%$ dwarf from one of the crosses. This shows that the parents are:

A
Hybrid tall and pure dwarf plant
B
Hybrid tall and pure tall plant
C
Hybrid tall and hybrid tall plant
D
Pure tall and pure dwarf plant

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 $Gg$?
