Whole animal expression patterns of Drosophila melanogaster CG32834, CG32833, and CG9897 and their orthologs in other congeners. F: female; M: male; g: genomic; N: negative control (water used as template). RpL32 is a ribosomal protein-encoding gene used as a control; primers for this gene were designed to span an intron to check for contamination of cDNA with genomic DNA. Gene names of the orthologs from conspecific species are given in figure 1. Note: (a) GF11310 is a D. ananassae homolog to the gene family but is not definitively orthologous with any one gene. GA25104 is a D. pseudoobscura homolog to the gene family but is not definitively orthologous with any one gene.
