My friend Pierre is red-green color blind and so is his father, but his mother is not color-blind. In the diagram below: a) Indicate the sex chromosomes of each member of Pierre's family b) Indicate the color-blindness allele associated with each chromosome of Pierre and his family (let B represent the color vision allele and let b represent a color blindness allele. If an allele cannot be determined with certainty, label the chromosome with a question mark c) Finally, determine the probability that Pierre's sister is color blind. Explain your reasoning.

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.
