Phylogenetic Analysis of Native Chicken from Bangladesh and Neighboring Asian Countries Based on Complete Sequence of Mitochondrial DNA D-loop Region by Mohammed A. Islam, Masahide Nishibori

“…The complete mitochondrial D-loop region was sequenced for a total of 18 individuals of Bangladeshi native chickens (BNC); full feathered (nana) (n＝7), naked neck (Nana) (n＝8) and Red junglefowl (RJF) (n＝3). The alignment of mitochondrial D-loop sequence of these chicken populations with 39 reference sequences from DNA databank; White Leghorn, G. g. murghi, G. g. bankiva, G. g. spadiceus, G. g. gallus and other Asiatic chickens was done to identify the phylogenetic position of BNC for the conservation and improvement of chicken genetic resource. …”
