Question

Would a trait that has only two distinct phenotypes more likely be a single-gene trait or a polygenic trait? How do you know?

Answer 1

wow i love the answers on this

Answer 2

i’ll give you a hint: it would be single gene trait

Answer 3

Okay but how do you know

Answer 4

A trait with two distinct phenotypes likely would be a single-gene trait. Because each gene of a polygenic trait often has two or more alleles, a polygenic trait can have many possible genotypes and phenotypes.
