State the basic requirement for sexual reproduction? Write the importance of such reproductions in nature.
The basic requirements for sexual reproduction:
Sexual reproduction involves fusion of male and female gametes coming from both the parents. In the sexual reproduction, a new individual is formed by the fusion of two haploid gametes, one from the male parent and the other from the female parent.
The importance of sexual reproduction:
(i) The Combination of DNA from two different individuals lead to increase in genetic variation in the offsprings.
(ii) This leads to diversity in the population which helps in natural selection.
