Vedclass · Answer

(C) According to Mendel's law of dominance,when a homozygous tall plant $(TT)$ is crossed with a homozygous dwarf plant $(tt)$,all the offspring in the $F_1$ generation will be heterozygous tall $(Tt)$.Since the allele for tallness $(T)$ is dominant over the allele for dwarfness $(t)$,the phenotype of all $F_1$ individuals will be tall.Therefore,the percentage of dwarf progeny in the $F_1$ generation is $0 \%$.

When a homozygous tall plant is crossed with a homozygous dwarf plant,what is the percentage of dwarf progeny obtained in the $F_1$ generation by Mendel (in $\%$)?
