Question

Chances of inheritable and evolutionary changes are more in such species which reproduce by

• A. Parthenogenesis
• B. Fission
• C. Sexual reproduction
• D. All of the above

Answer 1

The correct option is C Sexual reproduction

• Sexual reproduction involves the formation and fusion of gametes.
• This requires formation of gametes with meiosis in diploid organisms or meiosis taking place in zygote if the organism is haploid.
• Due to meiosis, only 50% of the genetic material is passed to the next generation and fusion of gametes results in a unique combination of the genome.
• While asexual reproduction results in offsprings with exact genetic material as their parent reducing chances of variations.

So, the correct option is 'Sexual reproduction'.
