Table 1.

Genetic structure of the sampled A. florea and A. mellifera populations. N = number of colonies. k_e = estimated number of matings, AR = allelic richness, col/km² = colony density, H_E = expected heterozygosity, n = number drones inferred from worker sample, * physical drone samples on DCA (ke not applicable).
