Overview of broad expression patterns. For the core genes in each broad cluster, we summarize the array profile, the annotation profile (anatogram), the number of total and core genes in the cluster and show one image for each stage of embryogenesis for a single representative gene. Array plots show the distribution of scaled intensity scores: the blue line indicates the median value while the gray box gives the inter-quartile range. The green rectangle shows that staining patterns of all broad genes are remarkably similar immediately after gastrulation. The representative late stage embryos (boxed in red) illustrate the relative diversity into which each of these homogenous early patterns resolve.
