WebDec 22, 2014 · 1. Introduction. Range expansions often result in decreased genetic diversity and increased between-population differentiation with increasing geographical distance from the source population [1–3].Theoretical and empirical studies show that genetic drift and serial founder events are important mechanisms producing such patterns [4–7]. Webfounder effect the result of starting a new population with a low number of individuals (founders), so that their GENE POOL may not contain the same proportions of ALLELES for a particular LOCUS as in the original population.
