A color-blind man married a normal woman. Their daughter, who was phenotypically normal, married a normal man and the couple produced three children, a normal boy, a color-blind boy, and a color-blind girl. Further examination indicates that this girl has two X chromosomes. Explain the origin of the color- blind girl.

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.
