$1:1$

Vedclass · Answer

(A) $1$. The cross between pure tall $(TT)$ and pure dwarf $(tt)$ plants results in an $F_1$ generation where all plants are heterozygous tall $(Tt)$.$2$. When $F_1$ plants $(Tt)$ are self-pollinated,the $F_2$ generation is produced with the genotype ratio $TT:Tt:tt$ as $1:2:1$.$3$. Among these,the true-breeding (homozygous) plants are $TT$ (tall) and $tt$ (dwarf).$4$. The ratio of true-breeding tall $(TT)$ to true-breeding dwarf $(tt)$ plants is $1:1$.

$A$ 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.
