Unveiling new perspective of phylogeography, genetic diversity, and population dynamics of Southeast Asian and Pacific chickens.

ABSTRACT: The complex geographic and temporal origins of chicken domestication have attracted wide interest in molecular phylogeny and phylogeographic studies as they continue to be debated up to this day. In particular, the population dynamics and lineage-specific divergence time estimates of chickens in Southeast Asia (SEA) and the Pacific region are not well studied. Here, we analyzed 519 complete mitochondrial DNA control region sequences and identified 133 haplotypes with 70 variable sites. We documented 82.7% geographically unique haplotypes distributed across major haplogroups except for haplogroup C, suggesting high polymorphism among studied individuals. Mainland SEA (MSEA) chickens have higher overall genetic diversity than island SEA (ISEA) chickens. Phylogenetic trees and median-joining
