Phylogenetic Relationship of the Genera Aethalops, Balionycteris and Chironax inferred from partial mitochondrial DNA cytochrome oxidase I (COI) Gene

This study was done to investigate the phylogenetic relationship among three genera of fruit bats, namely Aethalops, Balionycteris and Chironax. Twenty samples were analysed using 478 base pairs (bp) of partial mitochondrial DNA cytochrome oxidase I (COI) gene. The samples were collected from eight...
