Average diversity across the sparrow genome. ZAL2 and ZAL2^m refer to average π within the inversion interval on each chromosome arrangement and ZAL2/2^m† indicates the region outside the inversion on white-throated sparrow chromosome 2. They are shown for reference. A. Average genetic diversity (π) per locus. B. Average genetic diversity (π) for each chromosome type is calculated from concatenated sequences from all loci within that chromosome type. Error bars represent 95% CI (± 1.96 × SD). Note that the chromosomes labeled as Chr refer to the predicted orthologous chromosome in chicken.
