Question:

What are the advantages of sexual reproduction over asexual reproduction?

Answer:

Reproduction is a process to produce a young one similar to their parents genetically or morphologically. There are two modes of reproduction:- asexual or sexual reproduction.

Sexual reproduction is the process of forming a diploid cell zygote from one haploid male gamete or one haploid female gamete. In this two parents are involved, and when a offspring is formed than variation occurs and variation is the key factor of the evolution. If there is no variation, population cannot respond to the changing environment and may face an risk of being extinct from the environment. 

Asexual reproduction is the process of making two or more daughter cells from one parent cell, i.e, only one parent is involved. So, there is no variation occurs as in sexual reproduction occurs. It is dynamic, static where no evolution occurs in their morphological characters, where each offspring is genetically or morphologically identical to each other.

The long term survival period happens in sexual reproduction than asexual because of the variation. When genetic variation occurs, it helps the organism to survive in the drastic environmental changes.
