A colorblind man marries a normal-visioned woman and they have a colorblind daughter. a) What is the genotype for the man, woman and the daughter? b) The couple decides to have another child, what is the probability their child will be: i. Colorblind? Have a daughter that has normal vision, no colorblindness?

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.
