| Abstract | Cytogenetics applied to domestic animals is a useful biotechnology to be applied in the genetic improvement of livestock. Indeed, it can be used to select reproducers free chromosome abnormalities which are responsible for abnormal body conformation (aneuploidy), lower fertility (balanced chromosome abnormalities) or sterility (sex chromosome abnormalities). Cytogenetics may also be applied to assess environmental pollution by studying animals living in hazardous areas and using them as biological indicators (sentinels). Chromosomes also represent optimal biological structures to study the evolution among related (bovids) and unrelated (bovidshumans) species, especially using comparative FISH-mapping which is one of the most powerful tools to establish the correct order of loci along chromosomes. These comparisons allow us to transfer useful information from richer genomes (human) to those of domestic animals. Moreover, the use of specific molecular markers and the FISH-technique on both mitotic and extended (fiber-FISH) chromosomes, has heralded a new era of cytogenetics, allowing swift extension of genetic physical maps, better anchoring of both linkage and RH-maps to specific chromosome regions, and use in a variety of applications (clinical cases, embryo and sperm analyses, evolution). In this study a brief review of these fields of the animal cytogenetics is presented. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
