Quizplus · Accepted Answer

When a trait is influenced by multiple genes, it is referred to as polygenic inheritance. This means that the trait is not controlled by just one gene (monogenic), but rather by a combination of genes that interact with each other and with the environment to produce the observed phenotype. Intergenic refers to the non-coding regions of DNA between genes, and intragenic refers to the regions within a gene itself.
