Explain how sexual reproduction gives rise to more viable variations than asexual reproduction. How does this affect the evolution of those organisms that reproduce sexually?

In the case of asexual reproduction, only the minimal changes due to inaccuracies in DNA copying pass on to the progeny. Thus, offspring of asexual reproduction are more or less genetically similar to their parents. So, it can be concluded that evolution in sexually reproducing organisms proceed at a faster pace than in asexually reproducing organisms.

Sexual reproduction causes more viable variations due to the following reasons:

  1. Error in copying of DNA, which are not highly significant.
  2. Random segregation of paternal and maternal chromosome at the time of gamete formation.
  3. Exchange of genetic material between homologous chromosomes during the formation of gametes.
  4. Accumulation of variations occurred due to sexual reproduction over generation after generation and selection
  5. by nature created wide diversity.
