Fig. 2.

Sex chromosome expression is disrupted in hybrids relative to their conspecific chromosome. The proportion of expressed genes that are DE genes between hybrids and a single parent (musculus or domesticus). Positive and negative logFC indicate the proportion of expressed genes that were over or underexpressed in hybrids. Differences in the proportion of over/underexpressed DE genes and differences in the total proportion of DE genes (brackets) are indicated above each contrast (Pearson’s chi square test, FDR corrected P-values: *≤0.05, **≤0.01, ***≤0.001). SP = spermatogonia, LZ = leptotene/zygotene spermatocytes, DIP = diplotene spermatocytes, RS = round spermatids.
