A tall plant is crossed with a dwarf plant. In the progeny, about one half of the plants are tall and the remaining one half are dwarf. Determine the genotypes of the tall and dwarf plants:

Correct option is C

When a tall plant (Tt) is crossed with another tall plant (tt), the resulting progeny follows a Mendelian ratio of 3:1 for phenotype (tall:dwarf) and 1:2:1 for genotype (TT:Tt:tt). However, here, one-half are tall (Tt) and one-half are dwarf (tt), indicating both heterozygous tall parents (Tt × Tt).
