Question

asexual reproduction presents both advantages and disadvantages to bacteria. what is a disadvantage of asexual reproduction?
a rapid population growth
b lack of genetic variation
c slower population growth
d better equipped to adapt

Explanation:

• Option a: Rapid population growth is an advantage of asexual reproduction in bacteria, as they can reproduce quickly without a mate.
• Option b: Asexual reproduction in bacteria involves processes like binary fission, where the offspring are genetically identical to the parent. This lack of genetic variation means the population may struggle to adapt to new environmental challenges (e.g., new antibiotics, changes in temperature or nutrient availability), so this is a disadvantage.
• Option c: Asexual reproduction actually allows for faster population growth, not slower, so this is incorrect.
• Option d: Since there's little to no genetic variation, bacteria that reproduce asexually are not better equipped to adapt; in fact, the lack of variation hinders adaptation, so this is incorrect.

Answer:

b. Lack of genetic variation
