Fig. 5: Genome-wide selective sweep scan results using SweepFinder2 (shown in blue) and empirical exonic divergence (red).

The x-axis shows the position along each autosome (chromosomes 1–22), the left y-axis shows the composite likelihood ratio (CLR) value of the sweep statistic at each SNP, and the right y-axis shows the mean gene divergence at each SNP. The horizontal blue dashed line represents the null threshold for sweep detection, and the horizontal red dashed line represents the 75th percentile neutral divergence.
