Answer:
The correct option is A. The genetic variation introduced during recombination provides new allelic combinations for natural selection to act upon.
Explanation:
Recombination will lead to more possibilities for allelic combinations. This will result in increase in the number of genetic variations for a population.. The genetic variations in a population help the organisms to better adapt to different environmental conditions. If genetic variation is low for a population, then there are more chances for the population to become extinct or endangered when disasters occur. Many ecologists blame lack of genetic variation for extinction of different species.
