    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

  • Q4

    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
