what is genetic drift and natural selection
@All,well done!!
GENETIC DRIFT:-When the frequency of some genes gets changed in a small population due to some accidental reasons, such phenomenon is known as Genetic Drift. Genetic drift can give rise to different changes in sub-populations. It is random and rarely produces adaptations to the environment.
NATURAL SELECTION:- 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. Theory of natural selection was given by Charles Robert Darwin
