Population genetics of the Chilean frog Batrachyla Leptopus (Leptodactylidae)
Electrophoretic variation of proteins encoded by 14 loci was analyzed in eight (five continental and three insular) populations of the Chilean leptodactylid frog Batrachyla leptopus. The overall proportion of polymorphic loci was estimated to be 18.7% and the average number of alleles per locus, 1.2...

| description | Electrophoretic variation of proteins encoded by 14 loci was analyzed in eight (five continental and three insular) populations of the Chilean leptodactylid frog Batrachyla leptopus. The overall proportion of polymorphic loci was estimated to be 18.7% and the average number of alleles per locus, 1.2, while observed and expected heterozygosities were 1.7 and 5.1%, respectively. The estimated coefficient of genetic identity was 0.940; the corresponding figure for genetic distance was 0.063. F-statistics analysis showed a total inbreeding coefficient (Fit) of 0.855 and high levels of genetic subdivision (Fst = 0.596) as well as of inbreeding within populations (Fis = 0.640). However, there was only a moderate level of genetic differentiation (Fst = 0.181) between the insular group of populations and the continental group.<br>A variação eletroforética de proteínas codificadas por 14 loci foi analisada em oito populações (5 continentais e 3 insulares) da rã leptodactilídea chilena Batrachyla leptopus. A proporção geral de loci polimórficos foi estimada como sendo de 18,7% e o número médio de alelos por loco, 1,2, enquanto que as heterozigosidades observada e esperada foram 1,7 e 5,1%, respectivamente. O coeficiente esperado de identidade genética foi 0,940; o número correspondente para a distância genética foi 0,063. A análise estatística F mostrou um coeficiente de endogamia total (Fit) de 0,855 e altos níveis de subdivisão genética (Fst = 0,596), assim como de endogamia dentro das populações (Fis = 0,640). Contudo, houve apenas um nível moderado de diferenciação genética (Fst = 0,181) entre o grupo insular de populações e o grupo continental. |
