Laboratory Experiments About Bacterial Mutation Rates Have Demonstrated Which of the Following

question 10

Multiple Choice

Laboratory experiments about bacterial mutation rates have demonstrated which of the following?

• A) Bacterial mutation rates rarely evolve in short-term laboratory experiments; they are a relatively fixed feature of a species biology.
• B) In short-term laboratory experiments, bacterial mutation rates often evolve to be higher because higher mutation rates result in higher fitness.
• C) In short-term laboratory experiments, bacterial mutation rates often evolve to be lower because mutations are typically deleterious for organisms.
• D) Depending on the experiment, bacterial mutation rates sometimes evolve to higher rates, and other times evolve to lower rates.
