Which of the following best explains how genetic recombination influences evolution?

The answer is ‘ The genetic variation introduced during recombination provides new allelic combination on which natural selection to act upon’. For a population to be well adapted to an environment and its dynamic and random changes, it has to have a wide variation in genotypes and phenotypes. This way some individuals are able to survive drastic changes and pass their genes to the successive generations, that is if the majority of the population is not able to survive a calamity such as disease (bottleneck effect).
