Ancient British Isles
Genetic Space Analysis
Analyzing your genetic similarity to ancient British reference samples...
Preparing your genetic-similarity report
From the first hunter-gatherers who followed the retreating ice to the Norman kings who reshaped a kingdom, the British Isles have always been a crossroads of peoples.
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.
