Which method would be the most powerful approach to isolating a single mutant from a population of billions?

The most powerful approach to isolating a single mutant from a population of billions is positive selection.

The most powerful approach to isolating a single mutant from a population of billions is positive selection.

Further Explanation:

Positive selection is a kind of a process by which new genetic variants add in a population. Positive selection is also called as Darwinian selection. Positive selection is a main mechanism that Darwin predicts as giving rise to evolution and specific molecular genetics that are very hard to detect. Pioneering is a scientist who worked by Nielsen and Yang has provided a very powerful method for detect the positive selection at a sequence level

Mutations are difficult to identify and to analyze because the deleterious and neutral mutation predominate them in the frequency rate. To analyze a mutant from a very huge population can be done by positive selection. They detect single mutant by analyzing the frequency and nature of an allele diversity in a population.

six grader is what i am ssorry

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
