polygenic trait
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.
An example of hereditary variation is the difference in eye color among individuals within a family. This variation is influenced by genetic factors inherited from parents, where specific alleles determine traits like blue, brown, or green eyes. Such differences arise from the combination of genes passed down through generations, showcasing the diversity that can occur within a species.
These eye colors are phenotypic expression of genotypes for eye color.
evolution. variation and natural selection. DNA!!!!
Beagles can be brown, black ,tan, and white.
variation in which you get some features from your mother and some from father that are different (from others; ex. your sister has brown hair and you have blond hair)
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
Hair color is considered a discrete variable because it falls into distinct categories such as blonde, brown, black, red, etc. Each category is separate and distinct from the others, with no intermediate shades. In contrast, a continuous variable would have an infinite number of possible values within a range, which is not the case with hair color.
If you mean can it pass form one random person to another then no, but through your family that's how you get eye coulor. But what i find cool is some colours overpower others. Example: blue overpowers green.
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.
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.
Usually dark/light brown or green. It depends on where and when you're going. For example: If you were going in November, you should wear a light brown because the plants are dying.
