Mutations that make no difference to the fitness of the phenotype are called:
ANeutral mutations
BLethal mutations
CSilent migrations
DAdaptive radiations
Answer & Solution
Correct answer: A. Neutral mutations
1. The genetic changes caused by mutation can have one of three outcomes on the phenotype.
2. A change can help, harm, or make no difference at all.
3. Many mutations will also have no effect on the fitness of the phenotype; these are called neutral mutations.
4. Lethal mutations are the opposite extreme.
