If Several genes control human eye color. Because of this eye color shows a continuous variation from very dark brown to green to blue. What is this an example of?

This is an example of polygenic inheritance, where multiple genes contribute to a single trait, resulting in a continuous range of phenotypes. In the case of eye color, several genes interact to produce varying levels of melanin, leading to the spectrum of colors observed from dark brown to green to blue. This type of inheritance often results in quantitative traits, which exhibit continuous variation rather than distinct categories.
