✨ Finer European ancestry — continental populations, deeper panels
Your detailed ancestry breakdown can now place continental Western & Central Europeans, instead of collapsing them into "NW European" plus a spurious dash of Iberian and Tuscan.
- Six new reference populations — French, Orcadian, Sardinian, Basque, Northern Italian, and Russian — fill the gap where the reference set previously had only British, Iberian, Tuscan, Finnish, and a single catch-all NW-European group. A continental European's ancestry now lands on real anchors (French, Orcadian, …) rather than smearing across whatever was nearest.
- Deeper panels. The fine-population and PCA references are rebuilt at ~10× more markers (200,000 ancestry-informative sites, up from ~20,000). That sharpens the estimate and makes it agree more closely between a whole-genome file and a consumer-chip version of the same person.
- No action needed — the updated panels download automatically the next time you open the Ancestry tab, the same way reference genomes do.
A note on limits: frequency-based ancestry can't tell German from French or Northern Italian the way a haplotype service can — those national reference panels don't exist in open datasets. So a continental European may still show some "southern European" a commercial test wouldn't; the new French/Orcadian/etc. bins are the honest, real gain we can extract from open data.
Fixed — ancestry charts
- The donor-ancestry pie no longer renders broken for someone estimated at ~100% of a single continent — it was drawing a half-disc; now it's a full circle.
- Chromosome painting no longer invents ancestry you don't have. A donor who is 99%+ one continent could be painted with East-Asian or South-Asian stretches on a chromosome arm — noise from the local-ancestry model. Painting is now anchored to your overall composition, so a continent that's absent genome-wide won't show up locally.
- "Refresh" on the chromosome painting actually recomputes now, instead of re-displaying the cached result — so the fix above (and any future change) takes effect when you click it.
