Your X chromosome follows different inheritance rules from the rest of your DNA. Compare it with reference populations through K9 and K23 analysis, then explore the regional signals with their context and limitations.
Seven parts of the report, in the order you explore them. Composition is shown for each model with available results.
Start with the strongest population signals and the number of detected components for the available K9 and K23 results.
Understand the usual XY and XX inheritance patterns and why the X chromosome represents fewer family-tree branches than autosomal DNA.
Compare broad regional patterns and open each region for population-level percentages. Switch between the 9-category and 23-category models when both are available.
Read what the percentages mean, why the models can differ and why small components deserve caution.
Ask about your available K9 or K23 regional distributions with a separate AI Assistant licence. Answers can be inaccurate and are informational, not proof of ancestry or medical advice.
A concise card recaps the report's population signals, with a reminder that these are statistical similarity estimates.
Review the meaning of percentages, the tradeoff between the two model resolutions and the boundaries of the analysis.
A simplified K9 example and population-detail panel. The percentages are invented and do not come from a customer.
Invented percentages for illustration. This is not a customer result.
The largest signals in this fictional K9 example.
In this invented example, the K9 model assigns 42.0% relative similarity to the South European reference category. That percentage does not identify an ancestor or establish where relatives lived.
The real report groups populations into regions. Open a region to explore its component percentages.
Compare 23 reference categories instead of 9. Finer categories can add nuance, with greater uncertainty in small signals.
The two models are separate estimates. Differences do not identify or rule out a family relationship.
These are model categories for statistical comparison. They do not assign ethnicity, nationality or identity.
A broad view of population similarity across African, Asian and European categories.
A finer breakdown across regional reference groups. Treat small components as tentative.
The X chromosome follows specific inheritance pathways. General inheritance rules explain why its population signals can differ from your autosomal results; they cannot identify a particular ancestor from a percentage.
The X comes from the mother; the father passes a Y instead. The mother's X can include contributions from different branches of her own family tree.
One X comes from each parent. The father's X came from his mother, the child's paternal grandmother. Many other family-tree branches cannot contribute X-DNA.

A missing population signal does not disprove a family connection. Small percentages can reflect overlapping reference groups, limited coverage or statistical noise.

What the report compares, why results differ and how to read them with care.
It compares the X chromosome portion of your DNA with reference populations at two resolutions: K9 with 9 categories and K23 with 23 categories. Results are statistical genetic-similarity estimates, not proof of specific ancestors, ethnicity, nationality or identity.
The X chromosome follows different inheritance rules from autosomal DNA. Fewer family-tree branches can contribute X-DNA, and reference groups can overlap. Different regional signals are expected; a missing signal does not establish that a family connection is absent.
In the usual XY pattern, one X chromosome is inherited from the mother. In the usual XX pattern, one X comes from each parent, and the father's X came from his mother. These general inheritance rules do not identify a particular ancestor from a population percentage.
K9 compares 9 broad population categories. K23 compares 23 finer reference categories. The additional detail can increase uncertainty in small components. Both analyses are part of the report; available results depend on your sample and processing status.
Treat small values as tentative. They may reflect overlap between related reference populations, limited marker coverage, or statistical noise. A percentage is relative similarity within a model, not the contribution of a named ancestor.
No. The report is informational and does not establish family relationships, diagnose conditions or replace clinical testing. For genealogy, use it alongside documentary research and appropriate DNA matching.
Supported raw DNA files from testing companies such as 23andMe, AncestryDNA, MyHeritage and FamilyTreeDNA can contain X chromosome markers. Suitability depends on the file's X chromosome coverage; insufficient data can prevent an analysis.
Processing depends on your file and the current queue. You receive an email notification when your report is ready.
The report includes an optional AI explanation area, but using it requires a separate AI Assistant licence. Its answers are informational, can be inaccurate, and are not proof of ancestry or medical advice.
The purchase gives you ongoing access to the report in your account without a subscription. Results may be recalculated when the reference data or analysis method is updated. Optional AI access has its own licence terms.
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.
