(D) Let the gene for tallness be represented by $T$ and the gene for dwarfness by $t$.- $A$ heterozygous tall plant has the genotype $Tt$.- $A$ homozygous dwarf plant has the genotype $tt$.- The cross is $Tt 	imes tt$.- The gametes produced by $Tt$ are $T$ and $t$,and by $tt$ are $t$ and $t$.- The Punnett square results are:- $T 	imes t = Tt$ (Tall)- $T 	imes t = Tt$ (Tall)- $t 	imes t = tt$ (Dwarf)- $t 	imes t = tt$ (Dwarf)- The resulting genotypes are $50\% Tt$ (Tall) and $50\% tt$ (Dwarf).- Therefore,the percentage of dwarf plants in the progeny is $50\%$.

If a heterozygous tall plant is crossed with a homozygous dwarf plant,what will be the percentage of dwarfness in the progeny (in $\%$)?
