Answer:
sexual and asexual reproduction are two mechanisms that
produce offsprings of the living organisms. During sexual
reproduction, two types of gametes, known as male and female
gametes, are formed inside the male and female reproductive
organs, respectively. Diploid germs cells produce haploid
gametes by the cell division process called meiosis. During
asexual reproduction, diploid somatic cells are divided by
mitosis, in order to produce new diploid daughter cells. The
main difference between sexual and asexual reproduction is that sexual reproduction utilizes meiosis in the cell
division and fusion of haploid gametes in order to produce the diploid zygote whereas asexual reproduction
utilizes mitosis as their cell division mechanism, maintaining a uniform ploidy throughout all cell generations.

Any one of the following difference:
(i) In sexual reproduction two opposite sexes are involved where as in asexual reproduction only one individual is involved.
(ii) In sexual reproduction male and female gamete formation takes place where as in asexual no gamete formation occurs.
- Sexually reproducing organisms have better chances of survival
- Because more variations are generated.
