| Abstract | Evolutionary cytogenetics can take confidence from methodological and analytical advances that promise to speed up data acquisition and analysis. Drastic chromosomal reshuffling has been documented in birds of prey by FISH. However, the available probes, derived from chicken, have the limitation of not being capable of determining if breakpoints are similar in different species: possible synapomorphies are based on the number of segments hybridized by each of chicken chromosome probes. Hence, we employed FACS to construct chromosome paint sets of the white hawk (Leucopternis albicollis), a Neotropical species of Accipitridae with 2n = 66. FISH experiments enabled us to assign subchromosomal homologies between chicken and white hawk. In agreement with previous reports, we found the occurrence of fusions involving segments homologous to chicken microchromosomes and macrochromosomes. The use of these probes in other birds of prey can identify important chromosomal synapomorphies and clarify the phylogenetic position of different groups of Accipitridae. |

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.
