Vedclass · Answer

(A) $1$. In the $F_1$ generation,crossing $TT$ and $tt$ results in all heterozygous tall plants $(Tt)$.$2$. When $F_1$ plants $(Tt)$ are self-pollinated,the $F_2$ generation genotypes are $TT$,$Tt$,$Tt$,and $tt$ in a ratio of $1:2:1$.$3$. The phenotypes are $3$ tall plants and $1$ short plant.$4$. Among the $F_2$ generation,the pure tall plants are $TT$ (genotype frequency $1$) and the short plants are $tt$ (genotype frequency $1$).$5$. Therefore,the ratio of pure tall plants $(TT)$ to short plants $(tt)$ in the $F_2$ generation is $1:1$.

In peas,a pure tall plant $(TT)$ is crossed with a short plant $(tt)$. The ratio of pure tall plants to short plants in $F_2$ is
