From: Taxonomically restricted genes are associated with the evolution of sociality in the honey bee
Number of genes in honey bee OGS2 without homologs in other genomes. Although all 12 Drosophila genomes were used, only Drosophila melanogaster is shown because all Drosophila species had very similar numbers of homologs with Apis mellifera. Number of genes without homologs roughly followed taxonomic relatedness with the closely related ants having homologs for the largest number of Apis mellifera genes.
