Which of the following statements about asexual reproduction is not true?
Only one parent sex cell is needed.
The offspring are copies of the parent.
Most single celled organisms reproduce this way.
It results in more variation in species than sexual reproduction.

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?
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.
They are more likely to develop a variety of tail lengths.
They are smaller than lizards that reproduce sexually.

Cytoplasm, chloroplasts, and genes
Genes, chromosomes, and nucleus
Vacuoles, nucleus, and chromosomes
