World and Jewish Breakdown K28

World and Jewish Breakdown K28 is a modern-era genetic admixture calculator built for Jewish individuals who want a nuanced, regional view of their ancestry. The calculator compares your DNA to a curated set of Jewish and global reference populations to estimate proportional affinities across the landscape of historical Jewish communities and neighboring populations. It reports relative contributions from Ashkenazi, Sephardic, Mizrahi and dozens of regionally defined groups—such as Anatolian, East-Med, West-Asian, North-African, East-African, Caucasus, Balkan, Central-Asian and South-Asian—providing a multilayered portrait of ancestry rather than a single label. What it analyzes: allele frequency patterns are matched to reference panels to produce a probabilistic breakdown of ancestral components. The K28 model clusters genomes into fine-grained components optimized to separate Jewish subgroups and important surrounding populations, so you can see signals of Middle Eastern origin, Mediterranean and European admixture, African or South Asian connections, and Central Asian or Caucasus influences. Who it’s for: people of Jewish descent exploring family history, genetic genealogists, community historians, and researchers interested in modern Jewish population structure. It’s especially useful for those with mixed or uncertain heritage who want regional context beyond simple continental assignments. Insights you can gain: estimated percentages of affinity to specific Jewish communities and neighboring populations; clues about historical admixture events, migration routes, and regional endogamy or assimilation; and comparative context to interpret matches from other tests. The calculator emphasizes that results are probabilistic, shaped by available reference data and modern population structure. Why it’s valuable: by combining targeted Jewish reference panels with a broad global background, World and Jewish Breakdown K28 turns raw genotype data into an interpretable
