Quizplus · Accepted Answer

Polygenic inheritance involves the interaction of multiple genes to determine a single trait. This is in contrast to single gene inheritance (such as with autosomes or y-linked traits) or the expression of a single gene (as with structural genes). Genotype refers to an individual's genetic makeup, but is not specific to the inheritance of multiple genes.
