🧬 Dual Validation Framework
Curious experimental approach exploring two fundamentally different types of genetic relationships
Understanding the Two Relationship Types
Population Matches: Ancient individuals who had similar ancestry patterns to you (same demographic background)
Genealogical Matches: Ancient individuals who actually share DNA segments with you (family connections)
🔬 Live Analysis Progress
Completed: Chr1-4 (23.37 billion IBD segments analyzed)
In Progress: Chr5-22 sequential processing
4 of 22 chromosomes complete (18.2%) • Estimated 50+ billion total segments
🟦 Population Matches (ADMIXTURE K=10)
Ancient individuals with similar ancestry patterns • Cross-validated optimal K=10 (CV=0.51482) • 61,816 samples
I14900.AG
Nearly identical ancestry components to Nagy but zero shared DNA segments - proving population similarity ≠ genealogical relationship.
I14343_d.AG
Ancient Near Eastern ancestry pattern similar to Nagy's Middle Eastern/Levantine component structure.
I11095.AG
Bronze Age individual with similar Mediterranean ancestry component distribution.
HUGO_190_d.AG

⚠️ Experimental Archaic DNA Analysis
Preliminary Research: Initial hap-IBD protocols suggest potential archaic human DNA signatures in Chr1-5 analysis. This represents exploratory methodology requiring extensive peer review and validation.
Disclaimer: Archaic DNA detection methods are experimental and not scientifically validated. All findings should be considered preliminary research pending publication.
