Table 1 Summary of Orthonome analysis for D. melanogaster and five repleta group species. Average numbers of one-to-one orthologues (genes identified by Orthonome as having at least one orthologous relationship) are calculated based on pairwise orthologue predictions whereas total genes with orthologues and inparalogues are evaluated using the phylogeny-sensitive Orthonome analysis of all genomes
