Expression of D. melanogaster maternal gene orthologs. The percentages of previously identified D. melanogaster maternal genes which have detectable T. castaneum orthologs that are maternally loaded (Group A, black bar), only zygotically expressed (Group B, light grey bar), or not expressed (Group C, dark grey) in 0–24 hour eggs. Numbers of genes from sources are indicated in parentheses. Drosophila melanogaster data sources: (A) Berkeley Drosophila Genome Project in situ database [24,25], (B) Fly-Fish database [26], (C) Renzis, et al. [34], (D) Arbeitman, et al. [23].
