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 ... The model permits estimation of founding population sizes, changes in population size, time of population formation, and gene flow. Analyses of data from nine loci are consistent with the general portrait that has emerged from archaeological and other kinds of evidence.

The change in the frequency of a gene variant in a population due to random sampling of organisms. 3. Define founder effect. Occurs when a new colony is started by a few members of an original population. This can cause reduced genetic variation. 5.

The chances of a bead or allele being in the mix is 75%. This is because the founding population is a subset of the parent population, and thus contains a smaller amount of genetic variation.
