FIG. 4.
Box plots summarizing divergence comparisons. For all comparisons the ratio dN/dS is also broken down to display dN and dS alone. Top panels are between species comparisons of the fourth chromosome. Bottom panels are within species comparisons of the fourth chromosome (4th) to other regions of the genome experiencing a range in the amount of recombination (auto = nonheterochromatic autosomal loci, X = X chromosome loci, hetero = heterochromatic autosomal loci), as defined in Begun et al. (2007).
