The gene genealogy of csd alleles from three honey bee species. A total of 426 nucleotide sites in the coding regions of region 1 are used in tree-making. The neighbor-joining method with Kimura's two parameter distances is used. The number of alleles in each cluster is given in parentheses. Bootstrap percentages (from 2000 replications) for major clusters are shown on internal branches. Scale bars show the number of nucleotide changes per site.
