What would be a possible DISADVANTAGE of asexual reproduction?

• Ability to reproduce in the absence of a mate

• Results in a low genetic variation of the species

• Takes less time to produce offspring

• Allows for more genetic variation in the offspring

Which of the following is a TRUE statement.
