Comparison of sex bias in transcripts for zygotically transcribed genes (using the allele-specific zygotic definition) in D. pseudoobscura, D. miranda, and D. melanogaster, at one stage (late stage 5, or the end of blastoderm) early on in development, before the activation of MSL-mediated dosage compensation. Chromosomes are in the same order for all species, D. melanogaster has only the ancestral X, D. pseudoobscura and D. miranda both have XL and XR, and D. miranda additionally has the neo-XY chromosome (indicated with 3*). The neo-XY levels shown include those from both the neo-X and the neo-Y in males, and as many of these genes on the neo-Y are still producing transcript in males, this chromosome appears to have less female bias than the ancestral X chromosomes.
