Is Speciation Accompanied by Rapid Evolution? Insights from Comparing Reproductive and Nonreproductive Transcriptomes in Drosophila

Table 2

Number of genes present in each rate category when comparing D. melanogaster-D. simulans to D. yakuba-D. erecta and D. simulans-D. sechellia and to D. yakuba-D. erecta. Under brackets are the proportion of genes within tissue and the proportion within the rate category. Enrichment within a category was tested using χ 2, test and the Bonferroni corrections were applied [44].
