A. G. Konstandoglo, V. F. Foksha, T. O. Alexandrova

Results of antigenic spectrum analize of blood groups population of Red Estonian breed animals, in comparative aspect during 2 period of investigation - 1988 and 2009. For majority of antigenes the increase of the frequency occurrence was observed. Antigenes factors saturation increased to 25,3 %. Alleles pool AEB-locus was determined, in the 1-st period 71 alleles was discovered; in the II-d period - 78, 14 of which - was identical. The degree of modification genetic resemblance modification for 20-years period was 0,063 unit. The level of homozygosity has the tendency for lowering from 5,9 to 3,7 %. The population of Red Estonian breed animals became more homozygositic, the number of effective alleles increased from 16,9 to 26,6.
