Answer:
c. it leads to a redistribution of alleles
Explanation:
The gene flow can be defined as the movement of genetic material from one population to another within the same species. This movement may be associated 1-with the migration of individuals and subsequent reproduction of these organisms in the new population or 2-with the movement of gametes (eg., pollen dispersal) among populations. In both cases, gene flow is known to alter the frequency of particular alleles between populations and consequently also modify the evolutionary patterns of these populations.
