what is genetic drift
how is it different from natural selection?
Genetic drift is the change of allele frequency of a gene in a randomly mating population. Genetic drift may cause loss of alleles completely and reduce the genetic variation.
Genetic drift is different from natural selection in that, it is a random process, without having direction and there is no role of phenotype and environment whereas natural selection is driven by the environment and phenotype plays an important role. It may be defined as a process that results in the increased survival and reproductive success of individuals, who are well adjusted to the environment.
