| Abstract | Levels of genetic differentiation, gene flow, and genetic structure of three indigenous cattle populations (Luxi, Bohai, and Minnan) and two reference cattle populations (Chinese Holstein and Qinhai yak) in China were estimated using the information from 12 microsatellites, and 141 microsatellite alleles were identified. The mean number of alleles per locus ranged from 2.9005 in yak to 4.9722 in Holstein. The observed heterozygosity ranged from 0.5325 (yak) to 0.7719 (Holstein); 29 private alleles were detected. The global heterozygote deficit across all populations amounted to 58.5% (p < 0.001). The overall significant (p < 0.001) deficit of heterozygotes because of inbreeding within breeds amounted to 43.2%. The five cattle populations were highly differentiated (F st = 26.9%, p < 0.001) at all loci. The heterozygote deficit within the population was highest in Luxi cattle and lowest in yak. The average number of effective migrants exchanged per generation was highest (1.149) between Luxi and Holstein, and lowest (0.509) between Luxi and yak. With the application of prior population information, cluster analysis achieved posterior probabilities from 91% to 98% of correctly assigning individuals to populations. Combining the information of cluster analysis, gene flow, and Structure analysis, the five cattle populations belong to three genetic clusters, a taurine (Luxi and Chinese Holstein), a zebu (Bohai and Minnan), and a yak cluster. This indicates that Bohai black is closer to Bos indicus than Luxi cattle. The evolution and development of three indigenous cattle populations are discussed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
