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
INHERITANCE TRAITS - Traits or characters that we inherit from our parents or grandparents are called as inherited traits. For example - Eye Colour , Hair Colours.
ACQUIRED TRAITS - It is defined as the trait which produces the phenotype that results from environmental influences. Genes for these traits are not coded in DNA and therefore can not be passed to progeny from progeny. For example - sense of avoiding predators, knowledge etc.
