In a shocking discovery, biologists discover dragons! Dragon geneticists determine that flame eyes (F) are dominant to blue eyes (f) and burbling (B) is dominant to whistling (b). They suspect that the two genes are linked in one of the autosomes. They mate a true-breeding, flame-eyed, burbling female with a true-breeding, blue-eyed, whistling male. They then mate a pair of offspring.  a) Assuming dragon genetics follows the same rules as fruit flies, what ratio of phenotypes would you expect in the F2 generation if the genes were not linked? (Remember you are crossing FfBb x FfBb).   b) If the genes are linked, which of the  F2 phenotypes would occur at a lower frequency than would be expected if the genes were not linked?

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.
