WHAT IS GENE FLOW?
Gene flow (also called migration) is any movement of individuals, and/or the genetic information that they carry, from one population to another population.
GENE FLOW + ITS ROLE IN EVOLUTION
Gene flow includes many different types of phenomena, like pollen being blown to a new destination or people moving to new land masses. If gene combinations are carried to a population where those gene combinations formerly were non-existent, gene flow can be a significant source of genetic variation as this new population now has an altered (probably mutated) circling within the population. This cause genetic variation. Through interbreeding between populations, the gene frequency will be changed, having either a positive or negative affect on the population. Populations will grow but with larger genetic variation, they will have an increased chance of survival since they are better adapted to the environmental conditions.
Relative genotype frequency and relative allele frequency are the most essential measures of genetic variation. Relative genotype frequency is the percentage of individuals in a population that have a particular genotype. The relative genotype frequencies show the distribution of variation in different populations. Relative allele frequency is the percentage of all copies of a specific gene in a population that carry a particular allele. This is the most accurate measurement of the genetic variation in a population. A Punnett Square can help visualize a gene frequency in a population.
