When multiple genes affect a single phenotypic trait.Group of answer choicesepistasispleiotropyincomplete dominancepolygeniccodominancemultifactorial
Solution
The phenomenon where multiple genes affect a single phenotypic trait is known as polygenic inheritance. This is common in traits such as height, skin color, and eye color in humans. Each gene has a small additive effect on the trait, and the combination of these effects results in the continuous variation we see in these traits.
