Definitions:

Pleiotropy

A genetic phenomenon in which a single gene influences multiple phenotypic traits in an organism.

Polygenic Inheritance

A type of genetic inheritance where multiple genes determine a trait, resulting in a continuous range of possibilities.

Incomplete Dominance

Incomplete dominance is a genetic situation in which neither allele is dominant, resulting in an offspring with a phenotype that is a blend of the parental traits.

Codominance

A genetic scenario where two alleles are both expressed equally in the phenotype of the heterozygote, instead of one being dominant over the other.
