Figure 5. Over-expression of the X chromosome in sterile MxD hybrid mice.

(A) Average per chromosome deviation (log₂ scale) for each genotype versus the median per gene expression across all 12 males. The 19 autosomes (blue) are presented sequentially with the X chromosome (red). (B) Distribution of pairwise expression differences for the X chromosome versus the autosomes. For each pairwise comparison, the proportional distribution of gene-by-gene differences in mean expression (log₂) is shown for the X chromosome (red) and the autosomes (blue) with results from a Kolmogorov-Smirnoff test.
