When African and European Lineages Meet: The Genetic Landscape of Honey Bees in Argentina.

ABSTRACT: Argentina has a complex and diverse landscape of honeybee (Apis mellifera sp.) populations shaped by historic introductions and hybridization between Africanized (AHB) and European (EHB) lineages. While a latitudinal cline of Africanization has been documented, the adaptive consequences of this genetic admixture and its implications for local beekeeping practices remain poorly understood. In this study, we provide a more in-depth analysis of Argentine honeybee populations using recently published data from a panel of 272 SNP markers across five ecoregions to: (1) quantify how ancestry proportion (African A, European C/M) varies along geographic gradients, (2) assess whether ecoregion boundaries influence population structure, and (3) evaluate the potential trade-offs between AHB and
