From: Australian and Pacific contributions to the genetic diversity of Norfolk Island feral chickens
Neighbour-joining tree showing the relationships of mitochondrial DNA (200 bp) of chickens within haplogroup D. The geographical distribution of the subclades is presented in Figure 3. The term 'Pacific’ refers to the geographical region including Easter Island, Guam, Hawaii, the Philippines and Vanuatu, while mainland Southeast Asia (m.SEA) consists of Laos, Malaysia, Myanmar, Thailand and Vietnam. The coloured star highlights haplotype h213 in which ten Norfolk Island feral chickens and three Australian domestic chickens cluster. The red triangle indicates haplotype h231, which constitutes an ancient genetic signature of the Pacific by clustering ancient Easter Island and Hawaiian samples with Vanuatu chickens.
