Genome-wide analysis reveals differential admixture dynamics and historical demographic contractions in African cattle.

ABSTRACT: The rich cattle genetic diversity in Africa has been supporting livelihoods for centuries, providing food and nutrition security, income, and socio-cultural values. Understanding the genetic architecture of African cattle is essential for conservation and sustainable breed improvement. This study assessed genome-wide diversity, population structure, admixture patterns, and gene flow in 44 cattle populations across West, East, and Southern Africa, utilizing 63,655 medium-density SNP markers. Comparative analyses incorporated South Asian zebu and European taurine breeds for reference. Genetic diversity, estimated via observed heterozygosity and inbreeding coefficients (F_ROH), indicated higher variability in African zebu and admixed populations compared to African taurine cattle.
