Nucleotide position numbers are in accordance with the revised Cambridge Reference Sequence (rCRS) for the human. Owing to historical hybridisation and introgression events, the F clade savanna elephants have been found to carry only the mtDNA of forest elephant. Nucleotide variations in African elephant species (L. africana and L.cyclotis) are therefore displayed as F clade (present in both African elephant species) and S clade (present in only L. africana).
