Due to the high level of sequence divergence from other Apis clade species, as well as its basal placement in the species phylogeny, this approach of utilizing BLASTP searches to classify the putative origin of genes is not applicable to S. sabaudiense. These values are provided for reference only and are not included in the calculation of average percentages among Apis clade species as discussed in the main text.
