Not AvailableKaryotypic characteristics of Barilius bendelisis from Manipur, northeast India reported here revealed diploid count of 50 chromosomes having a karyotype of 16 metacentric, 14 submetacentric and 20 acrocentric chromosomes with fundamental arm numbers, NF = 80. The results were correlated to the available cytogenetic data and analyses the karyotype variations and chromosomal evolution that occurs in the same species of different geographical locations. No sex chromosomes were observed in the species and the comparative study corroborates the hypothesis of chromosomal evolutionary process like centric inversions were responsible for variation in the karyotypic structure in the species. The present study shows that basic information of chromosome number and morphology analysis, are no longer obsolete and can be used to compare the degree of chromosomal diversity over their geographical range, providing important tools for phylogeographic, evolutionary and taxonomic status besides increasing the existing cytogenetic data of the region.Department of Biotechnology, Government of Indi
