RNA-Seq data for: Evolution of sex-biased gene expression and dosage compensation in the eye and brain of Heliconius butterflies

RNA was extracted using Trizol from heads of 5 Heliconius species: H. erato, H. charithonia, H. melpomene, H. doris and H. sara. An illumina TruSeq kit was used to generate RNA-Seq libraries which were sequenced using 100 bp paired-end sequencing. Sequence data was used to compare gene expression between males and females within species. Differentially expressed genes were annotated for functions and compared across species. Data was also used to detect for dosage compensation in all species.
