DeCODE ancestry scan
From ISOGG Wiki
The deCODEme ancestry scan from deCODE genetics is only provided with the complete genome scan. The following screenshots provide examples of the ancestry results from a testee who has a small portion of Native American ancestry which appears in the test as "Asian DNA". Of particular interest is that deCODe display the entire X chromosome which 23andMe does not. In this particular case, this was a critical piece of information as the participant's "Asian" ancestry is pronounced on the X chromosome. The X chromosome has a particular inheritance pattern and this limits the possibility of who contributed that “Asian" DNA.
