Quizplus · Accepted Answer

Polygenic traits are determined by many genes working together to produce a phenotype. These traits often display continuous variation and are influenced by both genetic and environmental factors. Examples include height, skin color, and intelligence. Dominant and recessive traits are determined by individual genes, while polymorphic traits have multiple possible phenotypes within a population.
