Some aspects of genetic maps creation

Construction of genetic maps has a principal value upon practical using revealed associations "marker-character". Wide using molecular DNA-markers as well as application methodology identification and localization on chromosomes of QTL (quantitative trait loci) even in the case when it were no appearance new direction in science significantly allowed broadening of biological investigations, including precision and scalability in construction of genetic linkage maps. At the present investigation of gene linkage is one of most useful approach using for genome mapping as well as for genetic and breeding. Saturation of genetic maps gives possibility of compilation on map many segregated loci in one population up to full genome saturation. At the same time, effects of interaction "genotype-environment’ can be as basis for variability, which is one of main reason why different populations some of the species not revealed identical length of the maps and differences can reach up to 20%. Gene, loci or even full-length chromosomes mapped in organism of one taxon with high percent of significance can be evaluate and identify with the aim conservative molecular markers mapped in other organism as a rule from the related taxon. Moreover, if it are carried out interspecies comparisons of prediction on arrangement and mapping of genes or QTL, which was made for one species can be apply to other relative to him species.
