Phylogenetic relationships (maximum likelihood) of the honey bees (Apis spp) and Apis mellifera races based on the nucleotide sequence of 13 protein-coding genes of the mitochondrial genome (Crozier and Crozier 1993; Gibson and Hunt 2015; Hu et al. 2015; Haddad 2015; Eimanifar et al. 2016a, 2016b; Eimanifar et al. 2017a, 2017b, 2017c; Haddad et al. 2017; Nakagawa et al. 2017). The numbers at the nodes indicate bootstrap support inferred from 1000 bootstrap replicates. Alphanumeric terms indicate the GenBank accession numbers.
