Question 2: Which is a better mode of reproduction sexual or asexual? Why?

Class 12 - Biology - Reproduction in Organisms Page 17

Answer 1

Sexual reproduction is a better mode of reproduction. It allows the formation of new variants by the combination of the DNA from two different individuals, typically one of each sex. It involves the fusion of the male and the female gamete to produce variants, which are not identical to their parents as well as among themselves. These variations allow the individual to adapt to constantly changing and challenging environments. Also, it leads to the evolution of better suited organisms which ensures greater survival of a species. On the contrary, asexual reproduction allows very little or no variation at all. As a result, the individuals produced are exact copies of their parents and exactly similar to each other as well.

Answer 2

Hey there,

Well let's compare the two modes of Reproduction :-

★What happens in asexual reproduction???

It is just the production of progeny who is genetically similar to parents without producing any variation.

So , no variation means no evolution and hence it's obvious that it's not better mode of Reproduction.

★ Is sexual reproduction better mode of Reproduction???

My answer is yes. It is a better mode of Reproduction. because of the following reasons :-

• Progeny are not genetically similar to parents.
• Variations are produced.
• It give rise to evolution because of variation.

Thanks!
