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.
Brown eyes blue eyes and green eyes are an example of?
These eye colors are phenotypic expression of genotypes for eye color.

It is continuous, since there are unlimited numbers of shades between blonde, red, brown, and black.
How does sexual reproduction affect a population's genetic variation?
Sexual reproduction increases genetic variation within a population through the recombination of genes from two parents. This generates new combinations of alleles, increasing diversity and potentially increasing the population's ability to adapt to changing environments.

No, Chris Brown was not in Everybody Hates Chris. There are a number of spoof videos that parody Mr. Brown's troubles, some of them are called some variation of Everybody Hates Chris Brown.
Why do grizzlys have brown fur?
Grizzlys possibly have brown fur because of the adaptations it ancestors had gave it. For example thousands of years ago grizzly's could had have white fur but due to a genetical mutation in its DNA one of the grizzly's could have turned brown. Later on brown could have proved to be a dominant allele and by it reproducing after thousands of years less and less grizzlys of ,for example, white will become no more because brown could have helped it with survival so more and more grizzlys after reproduction become brown.
