$75 \%$ tall and $25 \%$ dwarf

Vedclass · Answer

(C) $1$. The cross between a pure tall $(TT)$ and a pure dwarf $(tt)$ plant results in $F_1$ generation plants that are all heterozygous tall $(Tt)$.$2$. When these $F_1$ hybrid plants $(Tt)$ are self-pollinated $(Tt 	imes Tt)$,the $F_2$ generation is produced.$3$. According to the Punnett square,the genotypes obtained are $TT$ (tall),$Tt$ (tall),$Tt$ (tall),and $tt$ (dwarf).$4$. This results in a phenotypic ratio of $3:1$,which corresponds to $75 \%$ tall plants and $25 \%$ dwarf plants.

When a pure tall plant is crossed with a pure dwarf plant,and the resulting hybrid plants are self-pollinated,what will be the phenotypic ratio of the offspring in the $F_2$ generation?
