Quizplus · Accepted Answer

Pleiotropic genes influence more than one aspect of a phenotype. This means that the same gene can affect multiple traits or phenotypes that may or may not be related to each other. For example, a gene that regulates the production of a certain hormone may affect both growth and immune function in an individual.
