WebbPolygenic inheritance also has quantum qualities, each type of multiple genes contributing similarly to plant species to determine the total number of contributing solutions as a pheno model. In humans, height, weight, skin color, examplestake it. WebbPolygenic traits are controlled by two or more than two genes (usually by many different genes) at different loci on different chromosomes. These genes are described as polygenes. Examples of human polygenic inheritance are height, skin colour and weight. Polygenes allow a wide range of physical traits.

WebbSee Answer. 1. Skin color in humans is determined by a polygenic inheritance system, possibly involving as many as 9 genes. For simplicity let’s consider the influence of 3 genes: A, B, and C, which show incomplete dominance for each allele that darkens skin color. Suppose a women who is AABbCc mates with a man who is AaBbcc. WebbSkin colour is a trait controlled by polygenic inheritance. Which statement is correct? [1 mark] A.
