A given organism has a gene A that produces a protein, cellular albumen, which traps water within cells. This organism lives is a cool, wet environment, and hence traps too much water in its cells. This organism thus has a reduced chance of both surviving and reproducing. When the organism dies -- and it dies owing to the effects of this gene -- this gene is eliminated from the gene pool. This is specifically an example of (pick the one best answer): A. genetic drift B. environmental selection sexual selection C. gene flow D. disruptive selection mutation

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.
