Albinism is a recessive trait in humans.A geneticist studies a series of families in which both parents have normal pigmentation and at least one child has albinism. The geneticist reasons that both parents in these families must be heterozygotes and that albinism should appear in 14 of their children. To his surprise, the geneticist finds that the frequency of albinism among the children of these families is significantly greater than 14. Can you think of an explanation for the higher-than-expected frequency of albinism among these families?

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.
