Question

In the genotypic explanation of dominance, what is the relationship between the T allele and protein production?

Options

• T allele produces a functional protein, resulting in the dominant trait

• T allele produces a non-functional protein

• T allele suppresses protein production

• T allele produces no protein at all

Answer 1

The T allele produces a functional (full) protein that results in the tall phenotype. The presence of at least one functional T allele is sufficient to produce the dominant phenotype in both TT and Tt genotypes.
