Skin color polygenic inheritance
Webb22 okt. 2024 · Skin color ; Polygenic traits are controlled by more than one gene and thus have many alleles that control them as well, such as hair color. ... Polygenic Inheritance Example, ... WebbPolygenic inheritance is different from single-gene inheritance, where one gene is responsible for the trait. With polygenic inheritance, the genes interact with each other to determine the trait. This type of inheritance is also referred to as quantitative inheritance because it produces traits that can vary in degree, such as height or skin color.

Webb15 feb. 2024 · Incomplete dominance occurs in the polygenic inheritance of traits such as eye color and skin color. It is a cornerstone in the study of non-Mendelian genetics. Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele.
WebbHuman height is controlled by multiple genes (polygenic), resulting in a bell-shaped spectrum of potential phenotypes. Environmental factors such as diet and health (disease) can further influence an individual human’s height. Another example of a polygenic trait that is influenced by environmental factors is human skin colour. Webb25 jan. 2024 · Polygenic Inheritance is found in both animals and plants.
