Web1115 Words5 Pages. Polygenic inheritance describes the inheritance of polygenic traits. A polygenic trait is a trait determined by more than one gene. Polygenic traits also have many possible phenotypes that are determined by the interactions among these several alleles. This type of inheritance is in contrast with Mendelian inheritance where ... WebPolygenic inheritance. Some characteristics are polygenic, meaning that they’re controlled by a number of different genes. In polygenic inheritance, traits often form a phenotypic spectrum rather than falling into clear-cut categories. Human skin color chart showing spectrum of skin pigmentation.

WebLooking at a real example of a human polygenic trait would get complicated, largely because we’d have to keep track of tens, or even hundreds, of different allele pairs. However, we can use an example involving the color of wheat kernels to see how Mendelian inheritance of multiple genes (plus a little incomplete dominance of alleles) can produce a … WebEye colour. Eye colour is also one of the most important polygenic traits examples in humans. The melanin composition in the front part of the iris is responsible for the eye colour. The more melanin deposited the darker colour is resulting, hence dark brown or black eye colour has more melanin compared to hazel or green eyes. the pioneering life of mary wortley montagu

WebNov 22, 2024 · Polygenic inheritance results in an additive effect of the genes on a single phenotype. Human skin color is primarily due to the presence of the pigment melanin in the skin. Melanin is not a protein, but it is the product of a biosynthetic pathway. Skin color is a polygenic trait and obviously demonstrates quantitative characteristics.
