  3. Mendel’s Theory of GeneticsDominant and Recessive Alleles • For the trait height in pea plants, T = tall and t = short. • If a plant has a T allele and a T allele (TT), would it be tall or short? tall • If a plant has a T allele and a t allele (Tt), would it be tall or short? tall • If a plant has a t allele and a t allele (tt), would it be tall or short? short
