| Abstract: | The genetic polymorphism of twelve enzyme systems in two parthenogenetic tetraploidArtemia populations from N. Greece has been studied, using starch gel electrophoresis. The genetic distance within and among the two Greek populations was calculated. The high degree of genetic identity between the populations indicates that they belong to the same species. Each is composed of electrophoretically identifiable clones; the fitness of these clones under different environmental conditions is discussed. |
