A species of mouse lives in California. One day 50 of these mice sneak onboard a boat and are taken to an island in the middle of the ocean with no mice on it. These mice find plenty of food to eat on this island and survive to produce fertile offspring even though this population has much less genetic diversity than the populations back in California. Over time on this island, a mutation gives some mice better night vision, and they start to hunt and eat insects that are only active at night and they sleep during the day. Another mutation gives some mice longer claws and they start to eat the seeds that only grow up in the tops of trees. What mechanism may lead to reproductive isolation and the eventual speciation in these mice? Group of answer choices Behavioral isolation Hybrid breakdown Gametic Isolation Mechanical Isolation Temporal Isolation

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.
