Well, a lot of factors contribute to the colour of peoples hair, E.G. Parents hair colour, where they live, etc. I reckon that the same amount of people have brown hair as the amount of people who have blond hair, ginger, red, black or any other colour. I personally have brown hair.
What else can I help you with?
What are the two recessive alleles for blue eyes?
Blue eyed people have two recessives for blue. It is expressed as bb. A person with brown eyes is BB. Brown is dominate over blue. However a person with brown eyes can carry the gene for blue and they would be called Bb.
Is it possible for a Chinese brown eyed and an American blue eyed have a blue eyed baby?

If a man had black hair and blue eyes and the woman had blond hair blue eyes can the child come out with brown eyes blond hair if the grandmother had brown eyes?
Blue eyes are a recessive trait. If at least one of the parents had a blue/hazel eyes with a mixture of blue and brown, then the couple's offspring could have brown eyes. If both parents had solid blue eyes, neither would have the dominant brown gene to pass to the baby, and it would have blue eyes, regardless of the grandmother's eye 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.

Why can a person with brown eyes carry blue eye alleles but a person with blue eyes cannot have a brown eye allele in their genotype?
A person with brown eyes can carry the blue eye allele because brown is a dominant trait, so they can have both blue and brown alleles in their genotype. However, a person with blue eyes cannot have a brown eye allele because blue eyes are a recessive trait, meaning they must have two copies of the blue allele in their genotype to express the trait.
Is it possible for a brown person to have blue eyes?
Yes, it is more uncommon than a brown person with dark eyes, but it is quite possible.
Are blue eyes more dominant than brown eyes?
No, brown eyes are more dominant than blue eyes genetically. Brown eye color is a dominant trait, while blue eye color is a recessive trait. This means that if a person has one gene for blue eyes and one gene for brown eyes, the brown eye gene will be expressed.
