Genetic Space Analysis
Your position among 525 ancient reference samples on a principal component map. Points that sit close together have similar genetic profiles.
Italy has long connected Mediterranean peoples, from early farmers to Roman citizens and medieval communities.
Principal component map
PCA reduces the N-dimensional ADMIXTURE reference panel to selected axes in a shared, reference-fixed ADMIXTURE PCA space. The chart currently shows the selected components. Variance percentages are global to that shared model and are not re-fit per report. Distance and filtering use the original N-dimensional ADMIXTURE values. Your kit is the gold diamond. This is not a Global25/Vahaduo plot.
Closest references in full ADMIXTURE space
This table is the non-visual equivalent of the chart and uses full-dimensional distance rather than apparent 2D spacing.

How to read this map
Principal component analysis (PCA) compresses many genetic measurements into a few axes that capture the largest differences between the reference samples. Each axis shows the share of variation it explains. Distances on the map are approximate; the table uses Admixture distance, where a lower value means closer similarity.
Being near a sample or group on this map indicates genetic similarity to that reference data. It does not show descent from a specific individual or population.
