Pbs Learning Media: Some Genes Are Dominant
This interactive activity, adapted from the Dolan DNA Learning Center, illustrates how Gregor Mendel used purebred yellow and green peas to show that some genes are dominant and others are recessive.

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.
