Answer:
Polygenic inheritance.
Explanation:
Polygenic inheritance is also known as multi gene inheritance that are included in the group of non epistatic gene. The genes of the polygenic tratit are additive in nature.
More than two different genes are involved in the polygenic inheritance. This inheritance controls the trait of the organism by multiple genes. Polygenic inheritance shows the different pattern as compared with Mendelian inheritance and environment also plays an important role in the polygenic inheritance. Human skin color is controlled by seven genes and hence referred as polygenic inheritance.
Thus, the answer is polygenic inheritance.
