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

(A) $=$ Sexual reproduction is a better mode of reproduction.
$\Rightarrow$ It involves the fusion of male and female gametes to produce variants which are not identical to their parents and themselves.
- These variations allow individuals to adapt to the changing environment and ensure a greater survival of the species.
$\Rightarrow$ On the other hand,asexual reproduction allows for little or no variation at all.
- As a result,the individuals produced are identical to their parent.
