Problem
Modern Greeks lack accessible tools to explore their Byzantine-era genetic heritage. Existing ancestry services focus on broad continental categories and miss the rich genetic substructure of the Byzantine world (330–1453 CE).
Approach
Built a comprehensive genomic analysis pipeline processing raw DNA data (MyHeritage ~700K SNP markers). Runs PCA with smartPCA/scikit-learn against the Allen Ancient DNA Resource (AADR v54+), supervised ADMIXTURE analysis (K=2–12 with cross-validation), genetic distance calculations (Euclidean + Fst), and haplogroup determination - all visualized in an interactive 6-page web dashboard.

Results
A working tool producing Byzantine ancestry composition reports. All screenshots show my own DNA results - Byzantine Score 62.04, Y-DNA haplogroup J2b-M12. Includes interactive PCA plots (West Eurasian overview, Mediterranean zoom, temporal animation), admixture bar charts, geographic heatmaps with Byzantine Empire boundary overlay, and haplogroup context.
