Abstract
Abstract An analysis of variability of blood plasma proteins in domestic Rein geese (Anser anser domesticus) and four species of wild geese [Anser albifrons (Se), A. indica (Lath.), A. caerulescens (L.), Chloephaga picta (Cmelin)] applying Polyacrylamide gel electrophoresis was performed. A comparative analysis revealed that natural and artificial selection caused evident differentiation not only among domestic and wild species, but among wild geese species as well. A slow homozygous form AlSS of locus. Al was very frequent among A. albifrons (Se) and A. anser domesticus geese, while among other species of geese this genotype was not found. 100% heterozygosis of Al and Pa loci was established in the population of Chloephaga picta (Cmelin). Most of the examined species possessed heterozygous genotypes of transferin loci, homozygous Tf DD and EE genotypes were found in no one of the examined species, and TfE alleles were found only in A. caerulescens (L.) geese with the frequency of 0.15. Artificial selecti...
