The results of observations carried out in different countries clearly demonstrate the steady tendency to increase the average annual temperature on the Earth during the last 150 years.1 For example, in the Russian Federation, in the next 15years, in the summer season, the temperature will rise by 1.4-1.50C in all grainproducing regions.2 In the next 40years, depending on the rate of increase of the greenhouse effect, the temperature will rise by 2.03.30C. In this connection, the creation of heat-tolerant and droughtresistant varieties and hybrids, the introduction of drought-resistant crops into agricultural production become extremely urgent problems of genetics and plant breeding.","PeriodicalId":260490,"journal":{"name":"Journal of Investigative Genomics","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134542219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is male specific and constitutively haploid. It passes from father to son, and, unlike other chromosomes, largely escapes meiotic recombination. Two segments (the pseudoautosomal regions) do recombine with the X, but this amount to less than 3 Mb of its ~60-Mb length, which makes it easier to study than the autosomes.1 These traits, explains its use in an increasing number of studies, especially those that address the history of the human population and makes it easier to study than the autosomes. Nevertheless, the Y chromosome continues to be overshadowed in these studies by the autosomal chromosome and mtDNA, despite containing far more genetic information than either. One reason for the lagging position of the Y chromosome has been a delay in the generation of useful data. The first PHYLOGENETIC TREE for human mtDNA was published in 1987,2 and the first for the Y chromosome was published in 1989.3 Since then, Y-chromosome-based studies have slowly accumulated; with the maturation of sequencing and genotyping technologies, a tremendous increase in all kinds of genetic data looms. It is therefore an appropriate time to reflect on what the Y chromosome can offer to population-genetic studies.","PeriodicalId":260490,"journal":{"name":"Journal of Investigative Genomics","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127035902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the investigation of the sequence data of mitochondrial DNA (mtDNA) control region revealed that taurine and zebu cattle diverged 200,000–1,000,000years B.P. and domestications of taurine and zebu cattle were two independent events that occurred separately 8,000–10,000years B.P. The genetic diversity, origin, conservation and sustainable utilization of these breeds received world-wide attention for a long time.1 Mammalian mitochondrial DNA shows several special features such as absence of introns, maternal inheritance, the existence of single copy orthologous genes, lack of recombination events and high mutation rate. Sequence comparisons of mtDNA D-loop region have been widely used to evaluate genetic diversity and phylogenetic performance among individuals and populations of cattle.2 Cattle are an important livestock species that have played a special role in the human history and culture, and had a considerable impact on human society.
