Question

How have gene frequencies changed in populations over time? Why did this occur?

Answer 1

Gene frequencies in a population is from a wide combination of genes and alleles. The existence of population after some time through changing situations relies upon their ability to adjust to moving outer conditions. In some cases the expansion of another allele to a populace makes it more ready to survive; now and then the expansion of another allele to a populace makes it less capable. Still different circumstances, the expansion of another allele to a populace has no impact by any means, yet the new allele will persevere over ages since its commitment to survival is impartial.
