| Abstract: | Ibex and chamois of the Alps – genetic variability and biochemical differentiation between species Genetic variability of 46 specimens of ibex (Capra ibex ibexL.) from Graubünden/Switzerland was investigated by means of horizontal starch gel electrophoresis. Twenty four isoenzyme systems were examined in kidney and liver tissues. From 38 loci scored 5.3 % were polymorphic (PGM-2, ADA-1) and average heterozygosity was 0.0235. The comparatively low proportion of polymorphic loci can be interpreted as the result of a bottleneck in alpine ibex during the last centuries. Based on a ¯-value of 0,2746 a time of divergence between ibex and chamois of about 1370000 years was calculated. |
