Skin Pigmentation in humans
Explanation: Polygenic inheritance- It is simply a single characteristic which is controlled by more than two genes. Human skin's color is determined by the amount of dark pigment it has which is melanin
. Minimum four genes are involved in the melanin production.
It is a case of continuous variation as the combination of melanin producing allele are responsible for degree of pigmentation
