Hair color is determined by multiple genes, not just one specific chromosome. Several genes contribute to the amount and type of melanin produced, which ultimately dictates hair color.
Here are some of the key chromosomes and genes involved:
- Chromosome 16: The MC1R gene on chromosome 16 is associated with red hair color.
- Chromosome 15: The HERC2 gene on chromosome 15 is involved in determining whether someone has brown or blonde hair. It also contributes to the difference between light and dark hair shades.
- Chromosome 6: The RPS6KA2 gene on chromosome 6 is linked to black hair color.
However, this is just a simplified overview. Scientists have identified more than a hundred genes that contribute to hair color variation. Moreover, environmental factors can also play a role.
