Vedclass · Answer

(D) In Mendelian genetics,a pure tall plant is represented by the genotype $TT$ and a dwarf plant by $tt$. When these are crossed,the $F_1$ generation consists of heterozygous tall plants with the genotype $Tt$. $A$ cross between an $F_1$ tall plant $(Tt)$ and a dwarf plant $(tt)$ is known as a test cross. The Punnett square for this cross $(Tt 	imes tt)$ is as follows: - Gametes from $Tt$: $T$ and $t$. - Gametes from $tt$: $t$ and $t$. - Offspring genotypes: $Tt, Tt, tt, tt$. This results in a phenotypic ratio of $50\%$ tall $(Tt)$ and $50\%$ dwarf $(tt)$.

$A$ cross between a pure tall plant from $F_1$ and a dwarf plant will result in:
