C)large.

Question

Quizplus · Accepted Answer

Inherently complex traits are often influenced by multiple genes and environmental factors. A single mutation is unlikely to have a large effect on such traits, particularly if it is a small change within one gene. Therefore, the most likely outcome is a small effect or no effect at all, especially in comparison to the overall complexity of the trait.
