Non-Mendelian Traits

Definition

These are traits that don't follow Mendel's laws and are not controlled by single genes with dominant and recessive alleles. Examples include multiple allele traits, polygenic traits, and codominance.

Codominance:

A relationship between two versions of a gene where both alleles are expressed equally in the phenotype of the organism.

Polygenic Traits: These are traits that are controlled by more than one gene, such as skin color or height.

Multiple Alleles:

This occurs when there are more than two possible alleles for a particular trait.
