A student reads that deer mice that have migrated to the hills of Nebraska originally had dark colored coats. Over many years, due to a mutation, the coat color of the mice changed to a lighter color to blend in easily with the sand. Which argument summarizes the mutation in deer mice? It is a beneficial mutation as it helped the mice survive in their new surroundings. B) It is a harmful mutation as it caused a change in the original coat color of the mice. It is a neutral mutation as the change in coat color did not affect any body functions in the mice, and only helped the survival of deer mice living in Nebraska.

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.
