Certain species of whiptail lizards have only female individuals and no males. These lizards reproduce asexually. What is one disadvantage of asexual reproduction for these lizards?
They are smaller than lizards that reproduce sexually.
They are more likely to develop a variety of tail lengths.
A new population can be established by a single individual in a relatively short period of time.
All the members of a population are genetically very similar and less able to survive environmental changes.
