Skin color is a polygenic trait. A polygenic trait is one that is controlled by multiple genes. Each gene for skin color deposits no pigment, some pigment, or lots of pigment. The additive effect of the deposited pigment from each gene for skin color results in a whole spectrum (continuum) of color. Also, skin color is affected by the environment, which further increases the variation in human skin color.

Why 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?
Eye color is not an example of polygenetic traits. Skin color is. Eye color is rather simple as far as genetics go (in humans). Brown (B) is dominate and blue (b) is recessive. A person with blue eyes has to have to have both genes for the color blue (bb). A person with brown eye color can has both genes for brown (BB) or one for brown and one for blue (Bb). The blue is not expressed in this case with Bb. Some people have hazel eyes but this is a variation of the blue color.

What would be your clue that a character would have polygenic inheritance pattern?
