PopulationStructureEngine

Population genomics structure analysis engine for admixture modeling, PCA-based stratification, FST estimation, and genetic drift characterization.

Features

• Genome-wide PCA for population stratification visualization
• Admixture proportion estimation across ancestral populations
• Pairwise FST calculation between population pairs
• Heterozygosity and allele frequency spectrum analysis
• Genetic drift and bottleneck signature detection

Results

1000 ind × 10,000 SNPs; 5 populations; Mean FST=0.0335; Mean Het=0.256

Usage

pip install numpy scipy matplotlib
python population_structure_engine.py
