What determines hair color
Which parent determines hair color?
Is Hair Color Inherited from Mother or Father? Hair color comes from both parents through the chromosomes passed onto their child. The 46 chromosomes (23 from each parent) have genes made up of DNA with instructions of what traits a child will inherit.
What are three factors that determine hair color?
Eumelanin is a black pigment, and phenomelanin is a red or yellow pigment. Hair color is determined by three factors having to do with pigments: how much pigment is present, to what degree a eumelanin or phenomelanin is present and how close together the melanin (pigment) granules are.
Which parent determines hair type?
Both of your parents give you two pieces of genetic information, called alleles, that determine what your hair type will be. The two alleles from your biological father combine with two alleles from your biological mother, giving you four in all.
What determines hair and eye color?
The color of our hair, skin, and eyes is determined by the same thing: the amount of pigment they have. The pigment that causes dark hair, skin, and eyes is called melanin. Melanin is made in special cells in the body called melanocytes.
Is black hair dominant or recessive over brown?
Black hair is made from a subtype of the same pigment that makes brown and blonde. It is a dominant trait and less likely to blend with lighter pigments than brown hair. In other words, it’s more likely for a baby born to a brown-blonde pair to end up with light brown or dark blonde hair.
What is the rarest hair color?
Natural red hair is the rarest hair color in the world, only occurring in 1 to 2% of the global population. Since red hair is a recessive genetic trait, it is necessary for both parents to carry the gene, whether or not they themselves are redheaded.
What is the rarest eye color?
green
Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world’s population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide.
What is the rarest eye and hair color combo?

Are green eyes real?
Green eyes are the most rare eye color in the world. Only about 2 percent of people in the world have naturally green eyes. Green eyes are a genetic mutation that results in low levels of melanin, though more melanin than in blue eyes. Green eyes don’t actually have any color.
How do you get green eyes?
Green eyes are a genetic mutation that produces low levels of melanin, but more than blue eyes. As in blue eyes, there is no green pigment. Instead, because of the lack of melanin in the iris, more light scatters out, which make the eyes appear green.
What’s the least common eye colour?

Can two brown eyed parents make a blue eyed baby?
The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby.
What are violet eyes?
Violet is an actual but rare eye color that is a form of blue eyes. It requires a very specific type of structure to the iris to produce the type of light scattering of melanin pigment to create the violet appearance.
