Question

Quizplus · Accepted Answer

Continuous variation refers to a trait that shows a spectrum of phenotypic expression across a range of values, rather than distinct categories. This suggests that the influence of multiple genes and environmental factors contribute to the phenotype, and individual genes do not have a large effect. Counting would be more appropriate for traits that show discrete variation, and it can be analyzed in individuals or populations.
