Definitions:

Recessive Allele

An allele that produces its characteristic phenotype only when its paired allele is identical.

Dominant Allele

A dominant allele is one version of a gene that masks the presence of a recessive allele in the pair, meaning the trait it represents is expressed even when only one copy is present.

Codominance

A genetic scenario where two alleles of a gene are expressed equally in the phenotype of the organism, neither being recessive to the other.

Polygenic Inheritance

Refers to the contribution of a variety of genes—sometimes very many—to a particular trait.
