The Tajima’s test indicated that the analysed population in balancing selection with a D-value of . A phylogenetic tree based on 455 bp of hypervariable mtDloop sequence classified 17 Bang Troi chicken individuals into three clades A, B, and E, which are common groups of Vietnamese and Asia indigenous chickens. This result provides the first genetic information and maternal lineages of Bang Troi chickens and it can support for registration of local chicken breeds. | ACADEMIA JOURNAL OF BIOLOGY 2024 46 1 49 54 DOI 2615-9023 18999 GENETIC DIVERSITY OF MITOCHONDRIAL DNA D-LOOP SEQUENCE IN BANG TROI CHICKEN BREED Nguyen Thi Dieu Thuy1 2 Dinh Thi Ngoc Thuy1 Mai Thi Thanh Nga3 1 Institute of Biotechnology Vietnam Academy of Science and Technology 18 Hoang Quoc Viet Ha Noi Vietnam 2 Graduated University of Science and Technology Vietnam Academy of Science and Technology 18 Hoang Quoc Viet Ha Noi Vietnam 3 North East College of Agriculture and Forestry Quang Ninh province Vietnam Received 25 September 2023 accepted 20 March 2024 ABSTRACT Bang Troi chicken GBT is a local chicken that is free-gardening raised in Quang Ninh province. A 1 268 bp of mitochondrial DNA mtDNA D-loop of 17 Bang Troi chicken individuals was sequenced and analyzed. Comparative multiple sequence alignment revealed 17 base substitutions within 17 Bang Troi chicken individuals. Bang Troi chicken had a relatively high level of genetic diversity expressed in the number of 13 haplotypes haplotype diversity of . The Tajima s test indicated that the analysed population in balancing selection with a D-value of . A phylogenetic tree based on 455 bp of hypervariable mtD- loop sequence classified 17 Bang Troi chicken individuals into three clades A B and E which are common groups of Vietnamese and Asia indigenous chickens. This result provides the first genetic information and maternal lineages of Bang Troi chickens and it can support for registration of local chicken breeds.
