The MC1R gene affects skin and hair color in humans.There are at least 13 polymorphisms of the gene inEuropean and Asian populations, 10 of which are nonsynonymous. In Africans, there are at least 5 polymorphisms of the gene, none of which are nonsynonymous.What might be one explanation for the differences inMC1R variation between Africans and non-Africans?

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
