Due to the event, the remaining population has a very low level of genetic diversity, which means that the population as a whole has few genetic characteristics. Following a population bottleneck ...

Genetic variation within a population is measured according to ... Consequently, the definition of populations can be refined to include groups of organisms whose genetic makeup can change over ...

The founder effect is an extreme example of "genetic drift." Genes occurring at a certain frequency in the larger population will occur at a different frequency -- more or less often -- in a ...

The Finnish population is one of the most genetically studied in the world. A relatively small number of founder individuals and strong genetic isolation over centuries have shaped the unique genetic ...
