Standard ancestry reports average across the genome. This one looks only at 13 centromere and low-coverage windows, then estimates which of 10 broad world regions those markers are most genetically similar to.
Each item below is a real section of the report, in the order you read it.
The report opens with the three world regions those windows are most similar to, with their percentages, so you get the headline before the detail.
Every region with a signal is listed from largest to smallest. Select a region to open its detail panel.
The same result drawn on a world map. Shading is a visual guide, not a border and not a claim about where your family lived.
Each region has context for the percentage: what the similarity estimate means, and a description of the region and its reference populations.
A chromosome view plus a table of chromosome, start and end for each of the 13 windows. You can see exactly which stretches the percentages come from.
Why centromeres and low-coverage stretches are harder to read, why the result can differ from a whole-genome estimate, and what the analysis cannot do.
An AI assistant can explain the regions and percentages in conversational language. Answers are informational, not proof of ancestry and not medical advice. It needs the separate AI Assistant licence.
A mock-up of the breakdown, a region panel, and the window table. The numbers and coordinates are invented.
Invented percentages for illustration. This is not a customer result.
Top three regions, shown in the report summary.
The 21.0% shown here would be the share of the analysed windows most similar to reference populations from this region. It is a similarity estimate, not a statement about where relatives lived.
| Chromosome | Start | End |
|---|---|---|
| Chr 1 | 10,000,000 | 12,000,000 |
| Chr 9 | 40,000,000 | 45,000,000 |
| Chr 16 | 20,000,000 | 24,000,000 |
The real table lists all 13 windows. These three rows are placeholders so you can see the layout.
Markers in the windows are compared against 10 continental-scale components. Each percentage in your report belongs to one of these.
Centromeres sit near the middle of a chromosome and are full of repeated sequence, so standard reads often cover them thinly. The report uses those stretches, plus a set of other low-coverage windows, and ignores the rest of the genome.
Use it next to a standard ancestry report, not instead of one. The windows can show a different regional mix because they are a small, harder-to-read slice of the genome.
Pick a sample already in your account, or upload a supported raw DNA file from a major testing company.
Only markers inside the 13 windows are compared with the 10-region reference model.
You get an email when it is ready. Your report stays in your account for lifetime access.

What the windows are, how to read the percentages, and how your data is handled.
It looks only at 13 predefined windows of your genome: centromeres and other low-coverage stretches on 10 chromosomes. It does not analyse your whole genome.
Each percentage measures statistical genetic similarity between markers in those windows and reference populations in one of 10 broad world regions. It does not prove descent, and it does not assign ethnicity, nationality or identity.
No. It is an ancestry and population-genetics report. It does not predict disease and is not medical advice.
Whole-genome reports average across chromosomes. This report uses a smaller set of windows that are harder to read and can carry a different similarity signal. A difference is expected, not an error.
Treat small values as tentative. They can reflect overlap between related reference populations, limited data in these windows, or statistical noise.
No. These windows are structurally hard to read in many DNA files. The report is a deliberate look at those windows, not a quality warning about the rest of your file.
The windows sit on chromosomes 1, 2, 8, 9, 10, 15, 16, 17, 21 and 22. The report lists each window as chromosome, start and end.
Yes. The report includes a chromosome view and a table of the coordinates that were analysed.
DNA Genics accepts supported raw DNA files from major testing companies, including 23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA and Living DNA, and supported whole genome sequencing formats.
Processing depends on your file and the current queue. You receive an email notification when your report is ready.
Your report is private by default, and your account provides controls for managing and deleting stored data.
The purchase gives you ongoing access to the report in your account without a subscription. Results may be recalculated if the underlying reference data or report method is updated.
DNA Genics has been building ancestry and DNA analysis reports since 2018. Our reports come from years of work with our own reference panels, calculators and ancient-genome comparisons, developed and reviewed by our team. They are not generated on the fly or assembled as a side project. We use AI only in clearly labelled optional features.
