Linkage between mitotype sequence and restriction site variation in 48 randomly sampled honey bee workers from San Diego County.

For cytochrome b, numbers denote one- (African) and two- (European) banded phenotypes after digestion with BglII. For CO1, numbers denote sequences that have a cytosine versus a thymine at position 2382. For COI—COII intergenic spacer sequences, numbers denote the frequency of previously described mitochondrial types (A = Africa, C = Carniola/Slovenia, M = Northern and Western Europe, and O = Oriental/Middle Eastern) determined by phylogenetic analysis (see S1 Fig).
