Quizplus · Accepted Answer

The typical distribution of a polygenic trait in a population is a bell-shaped curve, also known as a normal distribution. This is due to the fact that polygenic traits are influenced by multiple genes and environmental factors, leading to a range of possible phenotypes in a population. The majority of individuals in the population will cluster around the mean or average value of the trait, with fewer individuals exhibiting extreme values on either end of the curve.
