DNA and Reproduction Review Distance Learners

Which of the following is not a benefit of asexual reproduction?

• Offspring will be successful in an unchanged environment.

• Good at adapting to changing environments.

• Only requires one parent to produce offspring.

• Can reproduce rapidly.

In asexual reproduction, all of the offspring are:

• Not Identical

What is the big advantage of sexual reproduction?

• Can quickly grow the population

• Offspring are guaranteed to be successful in an unchanged environment.

• Only one parent is required to reproduce.

• Can adapt to changing environments
