qRT-PCR expression data for aromatase cyp19a1A and B in different East African cichlid species. qRT-PCR expression data for cyp19a1A and cyp19a1B are shown as mean normalized expression (MNE, calculated as described in Simon 2003) on a logarithmic scale tested in male and female brain tissue, testis, and ovary in species representing four major cichlid lineages (Haplochromini, Ectodini, Perissodini, and Lamprologini). Pseudotropheus pulpican is a species of Lake Malawi and Haplochromis obliquidens of Lake Victoria. All other species are from LT. Sample size is five for each tissue and sex except for Perissodus microlepis (only four males available and six females) and Altolamprologus fasciatus (only four males available).
