• B. In sexual reproduction, variations of two individual combine to form even more variations
• C. Variations among individuals give a species a better chance of survival
• D. All of these

Answer 1

The correct option is D All of these

Any cell division may give rise to variations among daughter cells. In sexual reproduction, the characters of two individuals come together because of fusion of gametes. More variation gives a group of individuals an advantage in adapting to an environment which may be changing. Hence, sexual reproduction is more advantageous than asexual reproduction.
