Question

Quizplus · Accepted Answer

A threshold trait is a trait that only expresses when a certain level or threshold of a given factor is passed. Cleft palate is an example of a threshold trait because it only expresses when a certain threshold of genetic and/or environmental factors is exceeded. Height, intelligence, blood pressure, and weight are not considered threshold traits as they do not have a specific cutoff point for their expression.
