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.
How does sexual reproduction affect a population's genetic variation?
It affects genetic variation, because the two parental organisms might have different alleles for each gene. For example, say a blonde eyed male and a brown eyed female reproduced, and the trait for brown eyes is dominant (Bb) and the blue eyes are recessive (bb). If they mated they would have the genotypes: Bb, and bb. Therefore, increasing variation

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.
What do pheasants wear?

How does the Brown Bear and a seagull benefit?
Brown Bears and Seagulls don't have any kind of relationship what so ever. But the seagull does benifit from the Brown Bear because when the bear eats its prey, it leaves the remains left for other scavengers to eat it. Take a fish for example, when the Brown Bear is done with its meal, it leaves what is left for the seagull to eat, like fish. This is an example of Commensalism because one benefits from the other without being harmed.
