- Abstract
Honey bee abdominal pigmentation is one of the most recognisable traits and it is often used by beekeepers as an indicator of M-lineage subspecies purity. However, this approach may negatively impact population diversity and is futile if there is no association between tergite colour patterns and the genetic background. To assess whether this trait can be used as a proxy for introgression proportions in M-lineage subspecies, we genotyped, with highly informative SNP assays, A. m. mellifera and A. m. iberiensis individuals displaying four different colour phenotypes. The SNP data detected highly introgressed bees exhibiting a black phenotype and, at the same time, pure or marginally introgressed bees with yellow banding patterns, in both subspecies. Despite these observations, contrary to A. m. iberiensis, in A. m. mellifera, introgression proportions revealed to be a significant predictor of abdominal pigmentation. Therefore, abdominal pigmentation could be used by A. m. mellifera conservationists to guide colony selection when genetic tools are unavailable.
