Mitochondrial and Y-chromosome DNA
Mitochondrial variation at the control region is posited to be low in dingoes, with over 50% of animals sampled in previous studies having a control region haplotype, A29, with all other samples only differing by one base pair (Savolainen etal., 2004; Oskarsson etal., 2011). This haplotype was shared with dogs from East Asia, South-East Asian islands and Arctic America (Savolainen etal., 2004). Similarly, only two Y-chromosome haplotypes (H3 and H60) were found in dingoes, the first shared with south-east Asian dogs and the second derived from Taiwanese haplotypes, shared only with the New Guinea singing dog (Ardalan etal., 2012). More recently, dingoes have been found to exhibit a unique chromosome haplogroup characterized by one single-nucleotide polymorphism and 14 single tandem repeats (Sacks etal., 2013).
