Definitions:

Recessive Inheritance

Pattern of inheritance in which a child receives identical recessive alleles, resulting in expression of a nondominant trait.

Dominant Inheritance

Pattern of inheritance in which, when a child receives different alleles, only the dominant one is expressed.

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.
