You were given 1000 fruit flies to start a new laboratory colony. Before starting to breed your fruit flies, you decided to determine their genetic make up. You counted approximately 360 fruit flies that have vestigial wings, a recessive trait. If you decide to remove all the fruit flies with vestigial wings and only breed the flies with normal wings, what is the approximate frequency of individuals with vestigial wings in the F1 generation? 0.09 O 0.16 0.25 0.36 O 0.14

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.
