DISCUSSION--Microsatellite Variation--In a captive breeding colony such as the one at the ASDM, the goal is to maintain as much of the founder population genetic signature as possible (Frankham et al., 1986; Ballou and Lacy, 1995; Mitchell et al., 2011) for potential reintroduction to the wild.
Factors that can improve the success of translocations include appropriate founder numbers, greater genetic diversity of founders, source of founder population, suitable habitat and size of the release area (Fischer and Lindenmayer 2000; Short 2009; Morris et al.
Founder mutations (those that occur more frequently or almost exclusively in a specific founder population group) account for a significant proportion of BRCA mutations.
The estimate is based on an analysis of the genealogy of an isolated founder population with more than 1,500 living descendants.

In conclusion, we present historical evidence that clarines the origin of the beavers introduced to southern Argentina and refutes the general assertion that 25 pairs constituted the founder population. We additionally show that restocking was a common practice in northern Manitoba in the 193 0s and 1940s.
A team of researchers from the Wellcome Trust Sanger Institute, the Broad Institute of MIT and Harvard and the Institute for Molecular Medicine Finland, found that a disruption of the gene TOP3B, an exceedingly rare occurrence in most parts of the world, is fairly common in a uniquely genetically distinct founder population from North-eastern Finland.
