Polygenic trait Pleiotropic condition 1:1:1:1 9:3:3:1 Expressivity = III = Digenic Mendelian ratio in the offspring when a heterozygote is test crossed. A single trait that is coded for by multiple genes. The degree to which a condition shows up in a population as a result of P = E + G Digenic Mendelian ratio in the offspring when two heterozygotes are mated. A single gene that can affect multiple traits.
