Question
This is when a trait is controlled by more than one gene.
- Complete dominance
- Incomplete dominance
- Co dominance
- Polygenic inheritance
Hint:
Polygenic inheritance
The correct answer is: Polygenic inheritance
A polygenic trait is a characteristic, such as height or skin color, that is influenced by two or more genes. Because multiple genes are involved, polygenic traits do not follow the patterns of Mendelian inheritance. Many polygenic traits are also influenced by the environment and are called multifactorial.
