Which form of microevolution involves the movement of alleles into or out of a population?
Show Understanding: • A gene pool consists of all the genes and their different alleles, present in an interbreeding population A gene pool represents the sum total of alleles for all genes present in a sexually reproducing population
Representation of a Gene Pool Understanding: • Evolution requires that allele frequencies change with time in populations
Mechanisms of Change Changes to allele frequency within a gene pool (evolution) can result from five key processes:

What is the movement of alleles into or out of a population?Gene flow is the movement of genes into or out of a population. Such movement may be due to migration of individual organisms that reproduce in their new populations, or to the movement of gametes (e.g., as a consequence of pollen transfer among plants).
What is the term for the movement of alleles into or out of a population through immigration and emigration?Gene flow is the transfer of alleles from one population to another population through immigration of individuals.
Is the flow of alleles in and out of a population?An important evolutionary force is gene flow: the flow of alleles in and out of a population due to the migration of individuals or gametes. While some populations are fairly stable, others experience more movement and fluctuation.
