Figure 3From: Taxonomically restricted genes are associated with the evolution of sociality in the honey beePercentages of Apis mellifera genes in taxonomically restricted categories with evidence for origin via gene duplication. A small percentage of genes in the most taxonomically restricted categories have paralogs that show homology to genes outside their taxonomic class. Hence, there is little support for most of these genes having formed via gene duplication followed by rapid sequence divergence. A much higher percentage of insect specific genes could, however, have evolved in this fashion, as a high percentage of such genes have paralogs that are widely conserved.Back to article page
