What are some examples of polygenic inheritance? |
Phenotypes of a given trait that are controlled by more than one gene are described as having polygenic inheritance; for example, in humans, it includes height, weight, skin color, and intelligence. Some congenital malformations (birth defects), like clubfoot, cleft palate, or neural tube defects, are also the result of multiple gene interactions.
