Founding population
Founder effect is the common outcome of the establishment of new populations from a small number of founding individuals. These founding individuals carry with them only a fraction of the genetic diversity of the parental population, and therefore, the founder effect results with a decreased genetic diversity and distinctive allele frequency ...
