People with red air have two copies of a recessive gene on chromosome number 4 which in turn causes a change in the MC1R protein. The MC1R protein is a protein that determines hair and skin color. Its a melanin-cide stimulating hormone receptor.

People with red hair have a genetic mutation in the MCIR gene that results in less eumelanin and more pheomelanin production in their hair. This leads to the characteristic red coloration. Red hair is a rare trait, with only around 1-2% of the world's population having naturally red hair.
