See the hypothetical pathway answer the following questions. A) If an individual is homozygous for a null mutation in the gene that codes for Enz1, what would the result be? B) What would happen if an individual is heterozygous for a mutation that abolishes the activity of Enz2? C) What could happen to the offspring of the individuals described above (in a and b)?  Assume that they only have the mutations described.

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.
