Like most features, hair colour is caused by a combination of your genes and your environment.
The genes involved in determining hair colour have not yet been fully worked out. We know that natural hair colour depends on the amounts of two substances in the hair: eumelanin and pheomelanin.
Blondes have a small amount of eumelanin; brown haired people have a higher level and black haired people have the most.
Pheomelanin determines how red your hair is: the more pheomelanin, the redder it is.
The amounts of these pigments depend on the genes you inherit from your parents, but they can also be changed by your environment eg if you spend a long time in the sun, your hair will bleach.
There are multiple genes that determine a persons skin tone. A white child can be born (rarely) to black parents and vice versa. If two white parents have a black child there must be an African ancestor. If two black people have a white child, the baby will be considered albino.
Genetics! Lets say the alleles for eye color are C and c. Parent A is homozygous dominant for green eyes, so they would have the genotype "CC". Parent B may be Homozygous recessive, meaning they have the genotype "cc". In this case, if you were to draw a Punnett square, you would find that the child would be Heterozygous, and they would end up with green eyes.*Heterozygous-the alleles are different (hetero) one dominant, one recessive. The genotype is "Cc". The child's phenotype ends up with the dominant gene. In order to determine breeding capabilities, create a Punnett square.
it depends where you were born like if you born in Africa your skin would be black because of the sun and heat a bit like a tan.
and that's gods way

What are eye color height weight hair and skin color examples of?
Those are examples of physical traits that vary among individuals and are determined by genetics. Eye color refers to the color of a person's iris, height and weight are measurements of a person's body size, hair color refers to the color of a person's hair, and skin color refers to the pigmentation of a person's skin.
Skin color in humans is a simple trait and is determined by only one pair of genes or alleles true or false?
False. Skin color in humans is a complex trait that is influenced by multiple genes, not just one pair of genes or alleles. Many factors, including genetic, environmental, and evolutionary influences, contribute to the wide range of skin colors observed in human populations.
What type of inheritance pattern best describes how skin color is determined?
Skin color is determined by multiple genes with a polygenic inheritance pattern. This means that several genes contribute to skin color, and the variation in these genes leads to a wide range of skin tones in populations. This inheritance pattern allows for a continuous spectrum of colors rather than distinct categories.
What would happen if humans had no earlobe?
It is extremely common for humans to have no earlobe to speak of . . . it is hereditary just like eye color or skin color.
What race has the strongest DNA?
Not really. While 2 white people won't have a black baby, and vice-versa, there is no such thing as a dominant and recessive trait for skin color. Skin color is determined by many alleles, which is the reason humans have such a wide variety of skin colors. Some are light, some quite dark, and others have a medium skin tone.
What controls variations skin color among humans?
The variations in human skin color is controled by the amount of melanin within the epidermis or outer layer of skin. Albinos, or persons with little or no melanin in their skin, have very pale, pinkish skin, regardless of the skin color of their parents.
What are eye color height weight hair and skin color examples of?
Those are examples of physical traits that vary among individuals and are determined by genetics. Eye color refers to the color of a person's iris, height and weight are measurements of a person's body size, hair color refers to the color of a person's hair, and skin color refers to the pigmentation of a person's skin.
Is skin an example of a polygenetic trait in humans?
Skin color.
Are There Green People On Earth?
No, there are no naturally occurring green-skinned people on Earth. Skin color is primarily determined by the amount of melanin produced in the skin, and green is not a natural skin color in humans.
Skin color of humans is controlled by?
Phenotype
What color was neanderthal skin or were the different by geography like us?
Studies suggest that Neanderthal skin color varied by geography, similar to modern humans. Genetic analysis indicates they likely had fair skin in regions with less sunlight and darker skin in regions with greater sun exposure. However, the exact skin color of Neanderthals is still debated among researchers.
Where does your skin get color?
Your skin gets its colour from the amount of melaninpresent in your skin as determined by your genetic makeup, and this comes from your parents.
What color is your skin?
The amount of melamine in the skin determines the color of the skin.Skin pigmentation is determined by melanin concentrations. Whether an individual is African or Caucasian, there is always melanin involved. (Only albinos lack melanin.)Well, you can have it, olive, brown, peachy yelowy colour black or blue. Blue is Smurfs.
Skin color in humans is a simple trait and is determined by only one pair of genes or alleles true or false?
False. Skin color in humans is a complex trait that is influenced by multiple genes, not just one pair of genes or alleles. Many factors, including genetic, environmental, and evolutionary influences, contribute to the wide range of skin colors observed in human populations.
Is skin color a phenotype?
Yes, skin color is considered a phenotype. Phenotype refers to an observable trait or characteristic of an organism, which in the case of humans, includes physical features like skin color. Skin color is influenced by genetic and environmental factors.
What type of inheritance pattern best describes how skin color is determined?
Skin color is determined by multiple genes with a polygenic inheritance pattern. This means that several genes contribute to skin color, and the variation in these genes leads to a wide range of skin tones in populations. This inheritance pattern allows for a continuous spectrum of colors rather than distinct categories.
What color are neanderthals?
There is no definitive answer to the color of Neanderthals' skin, hair, or eyes since they lived thousands of years ago. However, studies suggest they likely had fair skin, as they lived in regions with lower UV radiation levels. Hair and eye color likely varied among individuals, similar to modern humans.
