Biology Wise: Dominant and Recessive Traits in Humans
Explains what dominant and recessive traits are and how they work, and provides a list of single gene traits with the degree of manifestation if they are dominant or recessive. Also discusses co-dominance, incomplete dominance, polygenic...

Khan Academy: Multiple Alleles, Incomplete Dominance, and Codominance
In the real world, genes often come in many versions (alleles). Alleles aren't always fully dominant or recessive to one another, but may instead display codominance or incomplete dominance.
