This is one of Nancy's flowers which was supposed to be completely red. A genetic mutation has caused parts of the flower to be white instead. How common are genetic mutations?

Answer:

Actually, mutations are quite common. The average person has two mutated genes. A large percent of the time, those mutant genes don't do anything, because your DNA has built-in safeguards to help keep harmful mutations from causing problems. Even so, it is not at all unusual for them to pop up. Several of our fruits and vegetable strains, such as sweet corn and red grapefruit, are the result of mutations.
