Genetic studies Polynesian Dog

proposed route migration of dogs based on mdna. haplotype a29 relates australian dingo , new guinea singing dog, ancient polynesian arc2 modern polynesian, indonesian , ancient new zealand dogs, , ancient polynesian arc1 indistinguishable number of widespread modern haplotypes.

dna evidence indicates polynesian dogs descended domesticated dogs of southeast asia , may have shared remote ancestor dingo. study of mtdna show carried 2 haplotypes: arc1 , arc2.

in 2011, study looked @ 582 mdna base-pairs of mtdna control region of dogs malay peninsula , found 2 common dog haplotypes of indonesian region, in particular bali , kalimantan, mdna haplotype a75 (40%) , dingo founder haplotype a29 (8%). present haplotypes a120 , a145. 4 haplotypes fall within a2 mdna sub-haplogroup. study looked @ archaeological specimens of ancient polynesian dogs short-haplotype (263 mdna base pairs - nucleotide positions 15,458-15,720) derived. short haplotype named arc2 , corresponds mdna haplotypes a75 , a120, , found in 70% of samples found far away hawaii , new zealand. no dogs taiwan nor philippines carried dingo or polynesian haplotypes, indicates dogs did not enter pacific north-eastern route.

in 2015, study looked @ mdna sequences taken ancient new zealand dog samples discovered @ archaeological site @ wairau bar , found correspond a2 mdna sub-haplogroup. dog samples carried mdna haplotype a192, has been reported in modern village dogs bali, indonesia. when compared 2 ancient polynesian haplotypes arc1 , arc2, of wairau bar dogs matched arc2. dogs wairau bar represent part of initial population of dogs introduced new zealand, having arrived people around beginning of fourteenth century.

all of these dogs carry haplotypes fall under mdna a2 sub-haplogroup , therefore descendents of dog/chinese wolf hybrid ancestor. in 2015 comprehensive study of mdna haplotypes date found a2 sub-haplogroup represents 3% of dogs in south east asia, 22% in indian subcontinent , 16% in east asia.
