Question

Quizplus · Accepted Answer

Single gene traits are typically controlled by one gene and have a clear pattern of inheritance, which is not significantly influenced by the environment. However, complex traits such as human height are influenced by multiple genes as well as environmental factors like nutrition, exercise, and health. Therefore, complex traits have a significant environmental component.
