Hair color is the pigmentation of hair follicles due to two types of melanin: eumelanin and pheomelanin.Generally, if more eumelanin is present, the color of the hair is darker; if less eumelanin is present, the hair is lighter. Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color on the same person.
The Genetics of Our Natural Hair color. MC1R is the best-studied hair color gene in humans. Melanins are pigments derived from an amino acid called tyrosine. The color of the hair depends on the amount and type of melanin produced by melanocytes. Melanocortin 1 Receptor (MC1R) is the gene responsible for hair color determination.
The type and amount of melanin in hair is determined by many genes, although little is known about most of them. The best-studied hair-color gene in humans is called MC1R.This gene provides instructions for making a protein called the melanocortin 1 receptor, which is involved in the pathway that produces melanin.
Simply select known phenotypes (like color of eyes or hair) of child's father and mother and their grandparents and see the prediction. Note This heredity calculator uses simplified models to calculate traits and its certainty is far from 100% due to the fact that human genetics is far more complex than a simple mendelian dominant/recessive model.
Human hair in brown color is seen in many shades like brown-ebony, brown-mahogany, brown-oak, etc. These many shades of brown are due to the presence of an allele, a specific variation in the gene.
Basically, it is in five different colors: black, brown, blonde, red, grey and white. Let’s see a natural hair color chart below. human hair color chart Black hair.

Conclusion. Red hair color is not an example of a simple genetic trait. While the amount of red pigment may be mainly determined by one gene (MC1R), there are a large number of different MC1R alleles, and other genes affecting the amount of brown pigment that plays a major role in determining hair color.
Human skin color ranges in variety from the darkest brown to the lightest hues. An individual's skin pigmentation is the result of genetics, being the product of both of the individual's biological parents' genetic makeup, and exposure to sun.In evolution, skin pigmentation in human beings evolved by a process of natural selection primarily to regulate the amount of ultraviolet radiation.
The color of the baby's hair is determined by a set of genetic rules, known as Mendel's Laws. According to these genetic rules, the color of the hair is the result of the combination of two pairs of genes coming from each of the two parents. Depending on how these genes combine, the color of the hair will be different.
