A human protein, MC1R is responsible for telling human cells what type of pigment proteins to produce. One version of MC1R causes cells to make red pigments, while another version causes our cells to make black pigments. The red version causes red hair. The black version causes black hair. How did these 2 versions come to exist? gene flow mutation natural sclection genetic drift

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.
