| Abstract: | In plasma of the European starling (Sturnus v. vulgaris L.), genetic variation was detected by polyacrylamide gel electrophoresis. Two esterase zones, of which one is polymorphic, had already been described earlier. In addition to these two zones (Es-1 and Es-3), we describe a third (Es-2) that also showed variations. The distribution of the phenotypes observed in the Es-2 zone closely fits the expected distribution according to the law of random mating so that the polymorphism of Es-2 is hereditary. This Es-2 locus is postulated to be a codominant system, controlled by two alleles. |
