Vedclass · Answer

(B) In pea plants,the gene for tallness $(T)$ is dominant over the gene for shortness $(t)$. When a homozygous tall plant $(TT)$ is crossed with a homozygous short plant $(tt)$,all offspring in the $F_1$ generation have the genotype $Tt$. Since the tall trait is dominant,it masks the expression of the short trait,resulting in all progeny being tall.

Why is the progeny always tall when a tall pea plant is crossed with a short pea plant?
