My friend Pierre is red-green color-blind and so is his father, but his mother is not color-blind. In the diagram below: Pierre's Father Pierre's Mother Pierre Pierre's Sister а. 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, 2 ). 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.
