Teach polygenic traits and human eye color genetics with this complete, no-prep lesson! This engaging resource helps students understand how multiple genes (like OCA2 and HERC2) interact to produce real-world traits like eye color. Students explore continuous variation, gene interactions, and why genetics is more complex than dominant vs. recessive.
