(SSUAJF) Demo Report
This report isolates ancestry signals carried on the X chromosome. Results reflect specific maternal and paternal lineages and may differ from your autosomal ancestry. They are informational, not a record of individual ancestors.
The X chromosome follows a narrower path than autosomal DNA. Your results here describe similarity within that pathway only.
A male receives one X chromosome from his mother only. His father contributes a Y chromosome instead. X-DNA results for males reflect maternal-side lineages, including contributions from the maternal grandmother and grandfather along specific branches of the mother's tree.
A female receives one X from each parent. The paternal X came from the father's mother (paternal grandmother). The maternal X reflects mixed ancestry from the mother's side. This still excludes many ancestral branches that autosomal DNA includes.
Important: X-Chromosome results may differ from your main ancestry report. That is expected because fewer ancestors contribute X-DNA, and admixture models distribute similarity across overlapping reference groups.
Start with the broad regional pattern, then open a region for population-level detail. Switch between K9 and K23 when both are available.
8 population signals across 3 regional groups
7 population signals across 3 regional groups
X-DNA admixture is lineage-specific and informational. It complements, but does not replace, autosomal or haplogroup analysis.
Use the assistant to explore regional patterns for each available model. Each analysis uses only percentage distributions from your existing result.
This informational analysis uses only your K9 regional and percentage distributions. It does not use additional personal information or provide medical advice.

These results are statistical comparisons to reference populations on the X chromosome only.
A percentage indicates relative similarity to a reference component in this model. It is not a literal measure of one ancestor, nationality, or identity.
K9 uses nine broad groups for higher confidence. K23 adds finer detail across twenty-three reference populations, which can increase uncertainty in smaller components.
This report does not diagnose health conditions, establish family relationships, or determine ethnicity, culture, or citizenship.
Fewer ancestors contribute X-DNA. Your strongest X-Chromosome signal may reflect a related reference group that better captures shared variation in this narrower inheritance path.
Males inherit one X from their mother only. Females inherit one X from each parent, but the paternal X came from the father's mother. Both patterns weight maternal-side lineages more heavily than autosomal DNA.
Yes, when combined with X-DNA inheritance charts. X admixture helps contextualize population similarity along X-inheriting lines, but it does not replace segment matching or documentary research.
Treat small components as tentative. Compare them with broader regional totals and your autosomal reports before drawing conclusions.
