- Q1
What would be a possible disadvantage of asexual reproduction?
Ability to reproduce in the absence of a mate.
Takes less time to produce offspring.
Results in low genetic variation of the species.
Allows for more genetic variation in the offspring.

Which scenario is likely to result in the most diverse offspring?
Sexual reproduction between two individuals in the same population
Sexual reproduction between two individuals from different continents
Asexual reproduction by binary fission
Asexual reproduction by budding

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?
a hydra bud has half as much genetic material as the parent hydra
a hydra bud is genetically identical to the parent hydra
a hydra bud has different mutations than the parent hydra
a hydra bud contains genetic material from its two parents

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?
a new population can be established by a single individual in a relatively short period of time
they are more likely to develop a variety of tail lengths
all members of a population are genetically very similar and less able to survive environmental changes
the are smaller than lizards that reproduce sexually
