Question

Quizplus · Accepted Answer

In a polygenic trait, multiple genes contribute to the phenotype, and each allele can have a different impact on the trait. This means that there can be a range of phenotypic expressions, and no single allele is dominant. Additionally, the environment can also play a role in the expression of the trait, and there is no one gene that can cancel out its effect.
