Question

which is a disadvantage of asexual reproduction?
a. only one parent required to reproduce
b. quicker than sexual reproduction
c. there are many offspring in a short time
d. offspring are all genetically identical

Explanation:

To determine the disadvantage of asexual reproduction, we analyze each option:

• Option A: "Only one parent required to reproduce" is an advantage of asexual reproduction (no need for a mate).
• Option B: "Quicker than sexual reproduction" is an advantage (faster population growth).
• Option C: "Many offspring in a short time" is an advantage (rapid colonization).
• Option D: "Offspring are all genetically identical" is a disadvantage because low genetic diversity makes populations vulnerable to environmental changes (e.g., diseases, climate shifts) and reduces adaptability.

Answer:

D. offspring are all genetically identical
