These two reports are built for different purposes, so it's normal for them to show slightly different results.

Global Ancestry uses a chromosome-by-chromosome approach designed to detect small ancestry signals that might otherwise go unnoticed. It uses lower cut-off thresholds, so it can surface minor ancestral contributions that other reports would filter out.

Deep Ancestry is designed to give you a clear, stable breakdown across 100+ ethnicity and regional labels. It uses standard cut-off criteria (similar to Ancestry and 23andMe), so only the most significant contributions show up in your report.

If you see a small percentage (around 1% or less) in Global Ancestry that doesn't appear in Deep Ancestry, it's usually because of the different thresholds β€” not an error in your data.
