A typical characteristic of a quantitative trait is that it has a polygenic basis, meaning it is influenced by multiple genes. This leads to a continuous variation in the trait rather than a discontinuous distribution. Environmental factors can also play a role in the expression of the trait. A graph of the trait versus frequency often shows a normal distribution rather than two distinct peaks.
