Answer: Option C
:
C
The major forces that control the process of evolution are gene flow, genetic drift, mutation pressure and natural selection.
Gene flow is the transfer of alleles or genes from one population to another.
Genetic drift refers to a change in the frequency of alleles or genes in a population, due tochance events. Bottleneck effect and founder effect are two phenomena that increase the impact of genetic drift.
Bottleneck effect is the phenomenon by which natural disasters bring about a sharp lowering of a population’s gene pool.
Founder effect is a phenomenon by which a few members of the original population colonise a new location away from the old.
