7. HOW DOES THAT WORK? Eye color is a “polygenic” trait. poly: prefix meaning many, genic meaning genes. Many-gened. Up to fifteen different genes can have an effect on what color your eyes are! And that’s not counting the pigments and melanin (think skin color) levels that affect the final shade of their color.
