The main advantage of sexual reproduction over asexual reproduction is:
only one parent is needed.
all the offspring are identical.
there is greater diversity in the offspring.
more offspring are produced.
The Correct Answer is C
A. only one parent is needed: This is an advantage of asexual reproduction, as it is faster and less energy-intensive.
B. all the offspring are identical: This is a feature of asexual reproduction, but it is often a disadvantage because it makes the population vulnerable to environmental changes.
C. there is greater diversity in the offspring: Sexual reproduction reshuffles genes, creating unique individuals who are more likely to survive changing environments.
D. more offspring are produced: Asexual reproduction (like bacteria dividing) typically produces more offspring much faster than sexual reproduction.
