Population-genetic study of the polymorphism of structural genes and ISSR-PCR markers in some cattle breeds

Gorodnaya A.V., Glazko V.I.

The comparative analysis of genetic structures of five cattle breeds has been carried out using polymorphism of two different types of molecular-genetic markers – 20 structural genes and 128 DNA loci (the DNA fragments flanked by inverted microsatellite loci repetitions – ISSR-PCR method). In spite of availability of breed-specific singularities of genotype distribution detected by the both methods the level of mean heterozygosity of structural genes was similar in all the investigated breeds. A part of polymorphic loci and the average value of the polymorphic information contents (PIC) of ISSR-PCR markers has appeared much higher in commercial breeds with high effective number in comparison with Ukrainian autochthonous breeds. The population-genetic processes detected by different methods are discussed.
