Figure 3: Male and female SNP density and expression differences on guppy sex chromosome.

From: Convergent recombination suppression suggests role of sexual selection in guppy sex chromosome formation

Figure 3

(a) Moving average of male:female SNP density based on sliding window analysis (window size of 40 scaffolds). Ninety-five per cent confidence intervals based on bootstrapping autosomal estimates are in grey. (b) Male (blue) and female (red) expression of genes along the X chromosome (window size of 40 genes). Dark purple indicates the region of the sex chromosomes with the greatest X-Y sequence divergence, where coverage is significantly less in males (Stratum I, 22–25 Mb) (see Fig. 2), light purple indicates the region with less X-Y differentiation, where there is a significant excess of male SNPs (Stratum II, 15–22 Mb).
