IN SNAPDRAGONS, THERE ARE FLOWERS THAT PRODUCE RED PIGMENT AND FLOWERS THAT PRODUCE NO PIGMENT (WHITE). WHEN A TRUE BREEDING RED FLOWER IS CROSSED WITH A TRUE BREEDING WHITE FLOWER, THE RESULT IS 100% PINK OFFSPRING. WHAT IS THE MODE OF INHERITANCE? WHAT IS THE EXPECTED PHENOTYPIC RATIO (USE COLONS!)

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.
