Genetic differentiation among peripheral populations of Bombina bombina from Thrace and Anatolia: an allozyme analysis.

Genetic structures of Bombina bombina populations, located as peripheral isolates in Turkish Thrace and northwestern Anatolia, were analyzed by polyacrylamide gel electrophoresis using 20 allozyme loci, to investigate the populations' current genetic variation and possible colonization history. Significant genetic variability was detected in most of the loci and all populations. Allozyme pairwise F (ST) matrices and distribution of allele frequencies indicate their very close genetic relationships and relatively recent formation.
