Phylogenetic Studies on Red Junglefowl (Gallus gallus) and Native Chicken (Gallus gallus domesticus) in Samar Island, Philippines using the Mitochondrial DNA D-Loop Region.

ABSTRACT: A study was conducted to provide genetic information on the matrilineal phylogeny and genetic diversity of Red junglefowl (RJF) and native chickens in Samar Island, Philippines and to identify the genetic distance between Philippine junglefowls and other RJF species in Southeast Asia using complete mitochondrial DNA D-loop sequences. A total of 5 RJFs and 43 native chickens from Samar Island were included in this study. The results showed that Samar RJFs had a nucleotide diversity of 0.0050±0.0016, which was lower than those of three subspecies of Gallus gallus: G. g. gallus, G. g. spadiceus, and G. g. jabouillei. Meanwhile, Samar native chickens showed lower nucleotide diversity (0.0056±0.0004) than domestic fowls in some neighboring Southeast Asian countries, but higher than those in Afr
