Quizplus · Accepted Answer

Multifactorial traits are influenced by both genetic and environmental factors. Therefore, environmental factors play a role in determining the phenotype. The phenotypic distribution may follow a particular pattern, but it is complex and influenced by multiple factors, so it does not follow a simple dominant or recessive inheritance pattern. Only one gene does not determine the phenotype in multifactorial traits.
