Similarity, not lineage
Percentages describe statistical fit to reference populations. They are not shares inherited from named groups, and they do not establish descent or identity.

Low-Coverage DNA Report
Genetic similarity inside low-coverage windows
This report compares markers from 13 predefined windows, centromeres and other low-coverage stretches, with broad reference populations. It is a statistical genetic similarity estimate for those windows, not a whole-genome result and not proof of genealogy, ethnicity, nationality, or identity.

Chapter IV
Interpretation and methodology
Use these limits when you read the percentages. They describe similarity inside a smaller, harder-to-read slice of the genome.
Thirteen fixed windows
The comparison uses centromeres and other low-coverage stretches on chromosomes 1, 2, 8, 9, 10, 15, 16, 17, 21, and 22.
Lower data density
These stretches are harder to read than the rest of a DNA file. Small percentages are tentative, and disagreement with a whole-genome estimate is expected.
A complement, not a replacement
This report sits beside a whole-genome similarity result. It is not a health test, and estimates may change if the reference data or method is updated.
How this report is produced
- The selected sample is limited to 13 predefined centromere and low-coverage windows.
- Markers inside those windows are compared with broad world reference populations.
- A statistical model estimates how the window markers fit those reference profiles.
- The fit is shown as percentages, a map, and the window coordinates on this page.
Common questions
Does this mean the DNA file failed a quality check? No. The windows are structurally hard to read in many files. This report is a deliberate look at those windows, not a warning about the rest of the file.
Will these results differ from a standard ancestry report? They can, and that is expected. This report uses fewer markers in a fixed set of windows.
Is this a health report? No. It does not predict disease and is not medical advice.
