are polygenic traits affected by environment
Polygenic inheritance is a characteristic that is controlled by more than one gene (poly means many). Environmental impact on height in humans. An organism’s final appearance (phenotype) is a result of the interaction between the information held in its genotype and the effect of the environment acting on it during growth and development. Genotype + environment → phenotype. 1  Not all phenotypes are affected by environmental factors. Blood type, tongue rolling etc. are determined solely by genotype and are not changed due to other factors. 2  Poor diet is an example of an environmental factor which can affect a person’s phenotypic expression. 3  E.g.. Environment determines the phenotypic pattern of expression. Polygenic Inheritance Polygenic inheritance is a pattern responsible for many features that seem simple on the surface. Many traits such as height, shape, weight, color, and metabolic rate are governed by the cumulative effects of many genes. Polygenic inheritance.

Environment and Gene Expression Phenotypes are always affected by their environment. In buttercup ( Ranunculus peltatus ), leaves below water-level are finely divided and those above water-level are broad, floating, photosynthetic leaf-like leaves. Siamese cats are darker on their extremities, due to temperature effects on phenotypic expression. Polygenic inheritance Polygenic inheritance is a characteristic that is controlled by more than one gene (poly means many).

Yes, polygenic traits are affected by environment.
