If the phenotype reflects the activities of more than one gene, it is called a ______ trait.Multiple choice question.

The correct answer is polygenic trait.

Explanation:

A polygenic trait is one that is influenced by multiple genes, which means that more than one gene contributes to the phenotype of that trait. These traits often exhibit a range of phenotypes and are typically quantitatively measured. Examples of polygenic traits include human height, skin color, and eye color. In contrast, monogenic traits are determined by a single gene and typically have discrete forms. Understanding the genetic basis of polygenic traits is essential in fields such as genetics, breeding, and evolutionary biology, as it helps explain the variability observed in traits among individuals in a population.
