Chromosome breakdown — A more sensitive way to detect Indigenous DNA

This report analyzes all 22 chromosomes individually, rather than averaging your DNA into a single signal. By examining each chromosome separately, it can surface small or hidden Indigenous segments that may have been missed in previous ancestry tests.

Each of your chromosomes carries a unique part of your ancestry story.

As DNA is passed down through generations, chromosomes are reshuffled through a random process called recombination. Over time, this creates meaningful differences in which ancestral segments are inherited — even between siblings.

That’s why examining DNA at the chromosome level is essential for detecting ancestry that can be diluted or missed in broader analyses.

Unpack your ancestry at the chromosome level

This report analyzes all 22 chromosomes individually, mapping Indigenous ancestry directly along your genome to reveal signals that broader tests may miss.

See Indigenous ancestry in deeper regional detail

Using a high-resolution model and an expanded Indigenous reference dataset, the report provides up to 10 distinct Indigenous regional breakdowns across the Americas — offering more detail than standard ancestry tests.

Built with academic research expertise

Co-developed with population genetics partners from Stanford, this report combines rigorous research with accessible insights into Indigenous history, migration, and genetic inheritance.

The authors present a new simple, accurate, and easily trained methods for identifying and annotating ancestry along the genome (local ancestry). This method (XGMix) based on gradient boosted trees, which, while being accurate, is also simple to use, and fast to train, taking minutes on consumer-level laptops.
