There are several reasons to expect that rare species with restricted geographic distributions will have less genetic variation. First, loss of genetic variation caused by chance events (e.g., genetics and the founder effect) will be greater in smaller populations. In addition, species with restricted geographic distributions will occur in a limited number of environments and will therefore be less affected by natural selection to exist under different environmental conditions. Karron (1991) provided a very interesting test of this expectation by comparing the amount of genetic variation at allozyme loci in closely related species. He compared congeneric species from 10 genera in which both locally endemic and widespread species were present. One to four species of each type (rare and widespread) were used in each genus. In nine of 10 cases, the widespread species had a greater number of average alleles per locus.
