Question

Quizplus · Accepted Answer

Traits that are affected by many genes are influenced through polygenic inheritance. This means that multiple genes are involved in determining the phenotype, and variations in these genes can lead to a range of phenotypic expressions. Unlike traits that are controlled by a single gene, polygenic traits often exhibit a continuous variation, rather than discrete categories.
