If a person develops skin cancer because frequent exposure to sunlight induced a mutation in their skin tissue, the person: will pass on an increased chance of cancer to any children conceived after they acquired the mutation. will pass an increased chance of cancer to 50% of children because only 50% of gametes will receive the mutated chromosome. O will not pass on an increased chance of cancer to their children. O It's impossible to tell without knowing if the mutation is dominant or recessive

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.
