Polygenic Inheritance

English: Polygenic inheritance

Polygenic inheritance involves the expression of a phenotype that is being determined by many genes at different loci. Each gene exerts an additive effect. The effect of the genes is cumulative and there is no dominance and recessivity. There are many human characteristics that follow a continuous distribution in the general population, that closely resembles a normal distribution (that is a symmetrical bell-shaped curve distributed evenly around the mean).
