Key Genetic Findings

Two Deep Lineages

Overall FST = 0.47 separating Northern (A) and Southern/Coastal (B) ancestral groups.

3 At-Risk Breeds

Homor (Ne=28), Shageh (Ne=37), Sudan (Ne=39) — all below FAO conservation threshold.

Awadi–Awarik Unit

Lowest pairwise FST in dataset (0.019) — functionally one breeding population despite separate names.

173 Diagnostic SNPs

83.5% mean breed-ID accuracy using a 173-SNP AIM panel — suitable for field deployment.
