Figure 1. Multilocus HKA.

Figure 1

Summary of a multilocus HKA test, which compares polymorphism within D. melanogaster and D. pseudoobscura to divergence from D. simulans and D. miranda, respectively. Solid bars represent contributions to the overall χ2 test statistic caused by polymorphism levels at each locus; open bars represent contributions caused by divergence. Positive values indicate an excess of polymorphism or divergence relative to neutral expectations. Likewise, negative values indicate a defect relative to expectation.
