Quizplus · Accepted Answer

A quantitative trait is one that varies continuously from one individual to another, with no distinct classes or categories. This continuous variation is typically due to the influence of multiple genes and environmental factors. Therefore, choice B is the correct answer. Choices A, C, and D are incorrect because they suggest that a quantitative trait has distinct classes or categories or an asymmetrical frequency distribution, which is not true.
