Not even AncestryDNA, which has amassed more than 10 million samples, has enough to offer a “direct estimate of Aboriginal Australian ethnicity”. This means Aboriginal ancestors can only be reliably detected through direct maternal or paternal lines (using mitochondrial and Y-chromosome tests).

What blood type are Australian Aboriginal?

Results: The Aboriginal and non-Aboriginal populations had significantly different ABO and RhD distributions (P < 0.001). For Aboriginal individuals, 955/1686 (56.6%) were group O and 669/1686 (39.7%) were group A. In non-Aboriginal individuals, 1201/2657 (45.2%) were group O and 986/2657 (37.1%) were group A.
