The Science Of Red Hair And How To Look After It Mamabella Nowadays, red hair is found in all three celtic branches, although it is most common in the r1b l21 branch. the reason is simply that it is the northernmost branch (red hair being more useful at higher latitudes) and that the celtic populations of britain and ireland have retained the purest proto celtic ancestry (extremely high percentage of r1b). Red hair, also known as orange hair[citation needed] or ginger hair, is a human hair color found in 2–6% of people of northern or northwestern european ancestry and lesser frequency in other populations. it is most common in individuals homozygous for a recessive allele on chromosome 16 that produces an altered version of the mc1r protein.
Genetic Maps Of Europe Europe Guide Eupedia These migratory patterns significantly impacted the distribution and concentration of red hair within various ethnic groups. the genetic causes and biochemistry of red hair. i will explore the mc1r gene and its variants, as well as the ethnic origins of red hair and how these genetic factors contribute to the unique biochemistry of red hair. Red alert: scientists may have discovered what creates those gorgeous ginger tresses. you know that the coloring has been mythologized (and sometimes mocked) throughout history, but what you may not know is that for a long time, scientists didn’t exactly understand why some people have red hair. a new study published in the journal nature has. Red hair, also known as ginger hair, is a result of a genetic mutation in the mc1r gene, which affects pigmentation. this mutation leads to a decrease in the production of eumelanin, the dark pigment that gives color to the hair, skin, and eyes, and an increase in the production of pheomelanin, the red pigment. How it works. hair color comes from melanin, a pigment in your skin, hair, and eyes. if you produce a lot of the melanin type eumelanin, you probably have black or brown hair. if you don’t produce much eumelanin, your hair is probably blond. and, if you have low levels of eumelanin plus high levels of a red yellow pigment called pheomelanin.

There are two types of human melanin: eumelanin and pheomelanin. eumelanin ranges from brown to black in colour. pheomelanin ranges from red to pink. redheads have much more pheomelanin than eumelanin in their bodies. that’s why their skin tone is often so light, and why their hair is often reddish. In redheads, a genetic mutation in the mc1r gene leads to an increased production of pheomelanin and a decrease in eumelanin, resulting in the distinctive red color. the most common genetic mutation associated with red hair is the r160w variant, although there are several other known variants that can also contribute to this fiery hue.
