Abstract
Sympatric populations of the closely related sand goby species P. minutus and P. lozanoi were examined electrophoretically. Of 33 protein loci resolved, 3 were completely species diagnostic and 1 was virtually so. In samples containing, in all, 1051 P. minutus and 604 P. lozanoi, 5 individuals with a hybrid genotype at all these loci were found. One fish of unusual genotype at these 4 loci was discovered. On the criterion of the distribution of the alleles at these 4 loci the probability that this fish is an F1 hybrid is < 5 .times. 10-6; that it is a backcross, only slightly higher. This individual is most likely an F2 resulting from a cross between 2 F1 individuals.This publication has 1 reference indexed in Scilit:
