Polygenic Trait Aspects. Polygenic trait molding is done mostly with the environment and genes. More than one gene determines these traits, with each gene giving a small, yet additive effect. Multifactorial traits do not exhibit Mendelian ratios, and are determined between genes, or a gene, and the environment.olygenic Trait Aspects.

Two per poem would be enough. Use your own judgement. Sibilant WARNING: This is actually one of the most common sounds in English, so be careful to make sure the writer is deliberately using it for effect.
