$50\, \%$ tall plants and $50\, \%$ dwarf plants

(B) heterozygous tall plant has the genotype $Tt$. $A$ dwarf plant is always homozygous recessive with the genotype $tt$. When these are crossed $(Tt \times tt)$,the gametes produced are $T$ and $t$ from the tall plant,and $t$ from the dwarf plant. The resulting offspring genotypes are $Tt$ (tall) and $tt$ (dwarf) in a $1:1$ ratio. Therefore,$50\, \%$ of the offspring will be tall and $50\, \%$ will be dwarf.
