The Use of Isoenzymes in Tracing Evolution and in Classifying Drosophilidae

Abstract: Lakovaara, S. (Department of Genetics, University of Oulu, SF‐90100 Oulu 10, Finland), Saura, A., Lankinen, P., Pohjola, Liisa and Lokki, J. The use of isoenzymes in tracing evolution and in classifying Drosophilidae. Zool. Scr. 5 (3–4): 173–179, 1976.—Studies on the genetic constitution of natural populations of organisms have shown that these populations are extensively polymorphic at gene loci coding for enzymes. Much of this polymorphism detected by electrophoresing enzyme proteins is, however, not useful … Show more

“…between either local or geographically distant populations of these species. This is in good agreement with previous studies (Lakovaara and Saura, 1971;Lakovaara et al, 1976;Loukas et al, 1979;Pinsker and Buruga, 1982 Different trees can be constructed using either, or both, different measurements of genetic distance represents the data, although the "best fit" may not necessarily be the best hypothesis of evolutionary relationships. Therefore we have used several other criteria based on extraneous information concerning group taxonomy to judge tree reliability; these were, whether or not different populations of the same species clustered, the relative positions of D. madeirensis and D. guanche close to D. subobscura (Krimbas and Loukas, 1984) and the relative closeness of D. tristis and D. ambigua (Lakovaara et aL, 1972;Lakovaara and Keränen, 1980).…”

“…(b) To the utilization of electrophoretic techniques with very little discrimination efficiency. This is obvious from the very small differences in migration of the allozymes reported by Lakovaara et aL (1976) in comparison to those of the present study. The same cause could also explain the differences in electrophoretic phenotypes, between the present study and that of Cabrera et aL (1983) It could be argued that these differences are due to the fact that we used only one strain for D. madeirensis and one for D. guanche while Cabrera et aL (1983) used samples from natural populations.…”

“…Species which yielded allozymes with different mobilities are separated by semicolons, while a dash between two species denotes identical mobility of the corresponding allozymes. The data of Lakovaara et aL (1976) and Cabrera et aL (1983) presented here are restricted to the species in common with the present study: nine species for the first study [except for Acph, for which only seven species were studied (Lakovaara et aL, 1972) and Ao and Xdh, for which only eight species were studied (Lakovaara et aL, 1976)], and five species for the second study.…”
