Question

which of the following is a disadvantage of sexual reproduction? it results in genetic variation it results in identical offspring it requires much more energy than asexual reproduction it is much faster than asexual reproduction

Explanation:

1. Analyze each option:

• "It results in genetic variation": Genetic variation is an advantage of sexual reproduction as it helps in adaptation, so this is not a disadvantage.
• "It results in identical offspring": Sexual reproduction produces genetically unique offspring (as it involves fusion of gametes from two parents), while asexual reproduction produces identical offspring. So this is incorrect.
• "It requires much more energy than asexual reproduction": Sexual reproduction involves finding a mate, courtship, and the complex process of meiosis and fusion of gametes, which requires more energy compared to asexual reproduction (where an organism can reproduce on its own). This is a disadvantage.
• "It is much faster than asexual reproduction": Sexual reproduction is generally slower than asexual reproduction because of the processes involved in finding a mate and the reproductive cycle. So this is incorrect.

Answer:

It requires much more energy than asexual reproduction
