polygenic
Involving multiple genes
Polygenic describes traits influenced by multiple genes rather than a single gene.
Most human characteristics—height, skin color, intelligence, susceptibility to diseases like diabetes—are polygenic, with many genes each contributing small effects.
This contrasts with Mendelian traits controlled by one gene: Polygenic inheritance makes predicting outcomes far more complex.
