Definitions:

Polygenic Inheritance

The inheritance of traits that are determined by multiple genes, contributing to the phenotype in a cumulative or additive manner.

Dominant Inheritance

A pattern of genetic inheritance where only one copy of a gene from one parent is needed to express a certain trait, often overshadowing the other non-dominant gene.

Normal Behavior

actions or reactions of an individual or group that are considered typical or expected within a specific culture or society.

Recessive

A genetic characteristic that is expressed in an organism's phenotype only when two copies of the gene responsible for the trait are present.
