WebTwo or more genes may produce similar and cumulative effects on the same trait. In humans, the skin colour difference between so-called blacks and so-called whites is due to several (probably four or more) interacting pairs of genes, each of which increases or decreases the skin pigmentation by a relatively small amount.
