🧬 Ancient Matches: Dual Analysis Framework

Comprehensive analysis distinguishing between population similarity and genealogical relationships using both ADMIXTURE and IBD methodologies across ancient and modern genomes.

🔬 DUAL METHODOLOGY APPROACH

Analysis combining population genetics (ADMIXTURE) and identity-by-descent (IBD) methods across 61,816 ancient and modern genomes

🧬 Dual Validation Framework

Curious experimental approach exploring two fundamentally different types of genetic relationships

Understanding the Two Relationship Types

🟦 Population Matches (ADMIXTURE)
🟢 Genealogical Matches (IBD)

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

📈 EXPANDING WITH FULL GENOME ANALYSIS

IBD totals will increase as Chr5-22 analysis completes. This represents the largest individual ancient genomics analysis ever conducted.
