Brunettes, blondes and brown-haired around the world face feature: color their beards does not always match the color of the hair on the rest of the body, and sometimes to downright red. This phenomenon has a scientific explanation — genes. It seems that genes can explain everything. According to experts from the Dutch national information center for genetics and hereditary traits of Petra Haak-Blom, the difference in hair color is due to dominant genes, which are not always heard. Hair color on the whole body of man is not controlled by a single gene, and in some cases he appears defeated. Therefore, the color of hair in the armpits, on the feet, hands and in other parts of the body may differ from that on the head — and other body parts too. The genes that determine hair color, are so-called "incomplete dominant genetic traits". This means that there is no one single gene that is dominant over the other, but all genes influence each other, says Haak-Blom. Hair color white is pigmented polymers — melanin and they are two: the eumelanin (black pigment) and pheomelanin (red pigment). Cells dark-haired people contain only eumelanin, blond fewest eumelanin (if not to take into account albino) and red hair contain mostly pheomelanin. But melanin in the body can mutate. More than 10 years ago, the researchers found that one gene (MC1R) on the 16th chromosome plays an important role in creating the hair of red color. The task of MC1R is to create a protein called melanocortin-1. This protein plays an important role in the transformation pheomelanin in eumelanin. When someone inherits two mutated versions of the MC1R gene (one from each parent), eumelanin becomes fewer pheomelanin. Pheomelanin accumulates in the pigmented cells, and this leads to the fact that on the face appear red hair, but the skin no freckles. In simple words: if your friend red beard without freckles and everything else, could surprise him with something he's a bit of a mutant. Not the fact that it will make him a meme level Fassbender from "X-Men", of course, but he certainly can call himself special. medialeaks.ru/0211sts-pochemu-u-neryizhih-ryizhaya-boroda/

Fact! And your eyebrows can also be lighter than your hair color, the same as your hair color, or darker. My eyebrows became slightly darker than my hair color and my guy's eyebrows are lighter than his hair color :( Would be best if all hair matched on the body in my opinion! I don't like rainbow looks
