Abstract
A 307 bp segment of Cytochrome b gene of mtDNA was sequenced and analyzed for 90 individuals of Cirrhinus mrigala collected across the three rivers, namely Ganges, Narmada and Brahmaputra. Analyses revealed the presence of 14 haplotypes with haplotype diversity (h) ranging from 0.304 to 0.692, and nucleotide diversity (π) 0.002-0.043. The majority of variation was found within the population (96.21%), and the FST value (0.035) as well as the value of exact test of population differentiation (0.893) were found to be insignificant (p<0.05). Analysis of molecular variance (AMOVA) also indicated insignificant differentiation among sub-populations. Generally, low genetic differences were observed even though those populations were from different geographic locations. The present study suggests a single panmictic population of C. mrigala across the three rivers of India.
期刊介绍：
Previously published under the title DNA Sequence (Vols 1-19.3), Mitochondrial DNA accepts original high-quality reports based on mapping, sequencing and analysis of mitochondrial DNA and RNA. Descriptive papers on DNA sequences from mitochondrial genomes, and also analytical papers in the areas of population genetics, medical genetics, phylogenetics and human evolution that use mitochondrial DNA as a source of evidence for studies will be considered for publication. The editorial board will also consider manuscripts that examine population genetic and systematic theory that specifically address the use of mitochondrial DNA sequences.
