Question

Is eye color a discontinuous or continuous variation? Why is everyone saying that it's a discontinuous variation, when you obviously have a gradation of different colors around the world in the human population, and it's a polygenic trait determined by many genes! So shouldn't it be a continuous variation, just like hair color and skin color?

Since Jiskha does not have a regular biology tutor, you might try this site.

If there is a tutor here who can help you with this particular question, I'm sure he/she will add a response.
