GENETIC POLYMORPHISM OF SLOW–MIGRATING PREALBUMIN IN GEESE
Antoni Brodacki, El¿bieta Smalec
ABSTRACT
Blood serum proteins of 36 males and 71 females of parental generation and of 516 progeny of various breeds of geese were separated by means of thin–layer, horizontal, alkaline polyacrylamide gel electrophoresis. In the subregion of slow–migrating prealbumin (PASG) in alkaline gel, ten different phenotypes were found. It was determined, both in the parents and the progeny, that the genes of a single, autosomal locus encoded the proteins of this subregion, and the alleles were named: PASGA, PASGB, PASGC and PASGD, in order of decreasing speed of migration to anode. The PASGB allele was commonly found in all the studied geese, PASGA was found only in the geese derived from Anser anser, whereas the PASGC and PASGD alleles were present in the geese originated from Anser cygnoides.
Key words: genetic polymorphism, blood serum prealbumins.
