Accepted Answer

Results in low genetic variation of the species.

Answer

Ability to reproduce in the absence of a mate.

Answer

Takes less time to produce offspring.

Answer

Question 3

The hydra is a very small, simple animal that lives in water. Hydra reproduce asexually by budding, a process in which the bud breaks off an adult hydra and floats away. Which of the following best describe a hydra bud?

Question 4

Certain species of a whiptail lizards have only female individuals and no males. These lizards reproduce asexually. What is one disadvantage of asexual reproduction for these lizards?

Accepted Answer

Answer

a new population can be established by a single individual in a relatively short period of time

Answer

they are more likely to develop a variety of tail lengths

Answer

the are smaller than lizards that reproduce sexually
