Evolution.
Simply, evolution.
Simply, evolution.
Microevolution is the changes in allele frequencies due to mutation, natural or artificial selection, gene flow, and genetic drift. These changes occur over a long period of time within a given population.
Evolution is generally defined as "a series of changes over a period of time, resulting in something new arising". In particular, biological evolution is defined as "the change in frequency of alleles in a population's gene pool over a period of time".
One example of microevolution is genetic variation within a population. This occurs because of the accumulation of small changes in the frequency of alleles (alternative forms of a gene) over generations.
It is true that gene maps are produced by monitoring the frequency of the crossing-over between genes. Their changes and adaptations are use in the construction of a gene map.
cycles in population size over time; repeating changes in population size over time
