  • a The sample sizes for each locus and species.

  • b The genomic location of the gene in D. melanogaster. The physical maps of these species are all identical to each other and nearly identical to D. melanogaster with the exception of one inverted segment on the third chromosome (sections 84F-93F; Lemeunier and Ashburner 1976). The chromosome (X, 2, 3, or 4) is shown followed by the polytene chromosome band number (Bridges 1938) as listed in Flybase ( The mt:ND5 gene is located in the mitochondrial (mt) genome.

  • c The effective number of codons (Wright 1990). Values near the upper limit of 61 have a low codon bias, whereas values near the lower limit of 20 have a high codon bias. Values were taken from Kliman and Hey (1993b) or calculated from the complete coding portion of the gene as reported in the GenBank record. NA, not applicable; In(2L)t was positionally cloned and has no associated protein coding gene.

  • d The estimated recombination rate per generation as reported for D. melanogaster in the Appendix of Kliman and Hey (1993b). Units are centimorgans per kilobase pair.

  • e The average number of aligned base positions from all pairwise comparisons. Values are shown for total length, as well as for amino acid coding regions, and noncoding regions.
