1. Mutation - production of new alleles V 0 jate source for allele differences
LI Without mutation there would be no new variations among members of a population for natural selection to
L1 Remember that mutations are random. 2. Gene flow - movement of alleles from population to population
Movement of alleles among populations by migration of breeding individuals
Can increase variation within a population by introducing novel alleles from another population
Continued gene flow reduces differences among populations.
