Term
Microevolution
Definition
Changes in allele frequencies that occur over time in a population due to mutation, natural/artificial selection, gene flow, and genetic drift
Term
Genetic diversity
Definition
The total number of genetic characteristics in the genetic makeup of a species; important as a method of adaptation to changing environments
Term
Adaptation
Definition
The evolutionary process by which a population becomes better suited to its habitat
