It was shown the high similarity of gene orders of homeological chromosomes in compared species, with the exception of 9th and 14th chromosome pairs. <...> Cytogenetic techniques are an important tool in systematics and phylogeny of mammals (1-3). <...> In recent decades, the study of chromosome sets is a part of applied studies (4, 5), including the works on conservation and rational use of animal gene pools (6-10). <...> The analysis of cytogenetic similarities and karyotype evolution are described in number of scientific works (11-13). <...> Recent works on assessment of genomic similarity often use molecular genetic markers (14-19). <...> The comparison of genetic composition of individual chromosomes in different species was the subject of many studies (2028), as well as phylogenetic analysis based on comparison of gene maps (29-32). <...> The comparison of chromosomal structure revealed divergent pathways in cytogenetic evolution of sheep species (33-37). <...> The study of gene orders of Bos taurus L. and Ovis aries L. allowed a detailed analysis of their karyotypic divergence (32). <...> However, in all these studies the subjects were species with pronounced cytogenetic differences. <...> In this work the authors compared gene maps of two closely relative species – members of the family Bovidae with similar chromosome sets – Bos taurus L. and Capra hircus L., in order to find differences in organization of their genomes at the level of gene <...>
