thomaster · Answer

Gene flow =  the transfer of alleles or genes from one population to another.

Genetic drift = the change in the frequency of a n allele in a population due to random sampling.

Natural selection =  the process by which forms of life having traits that better enable them to adapt to specific environmental pressures.
