Fig 5. Expression levels (in FPKM) for unduplicated ancestral state for three D. yakuba reference replicates for genes that are duplicated in sample strains compared to expression levels for all genes.

FPKM values are indicative of ancestral expression patterns prior to duplication. Duplicated genes have higher mean and median ancestral expression compared to non-duplicated genes in female tissues (A) and male tissues (B). Genes that are duplicated have lower median expression in ovary compared to carcass in females (A) but there is no difference in expression in reproductive vs. somatic tissue in males (B). Plots shown exclude outliers.
