In pea plants, the allele for tall height, T, is dominant over the allele for short height, t. A pea plant has two different alleles for height. Which statement about the pea plant is correct?

Question

Responses

The phenotype for height is short, and the genotype is Tt.
The phenotype for height is short, and the genotype is Tt.

The phenotype for height is tall, and the genotype is Tt.
The phenotype for height is tall, and the genotype is Tt.

The phenotype for height is short, and the genotype is tt.
The phenotype for height is short, and the genotype is tt.

The phenotype for height is tall, and the genotype is TT.

Answer 1

In pea plants, since the allele for tall height (T) is dominant over the allele for short height (t), a plant with the genotype Tt will express the dominant phenotype, which is tall.

Therefore, the correct statement about the pea plant with two different alleles for height (Tt) is:

The phenotype for height is tall, and the genotype is Tt.
