Fig. 13

Combined plots of quantified gene expression patterns in the blastula stage. The main clusters from Fig. 6 are plotted in large diagrams. The small diagrams are subclusters within the large plot above them. The insets are in situ hybridizations from which a profile in the subcluster is derived. The expression domains that arise from the clustering are: central domain (Cd), central ring (Cr) and external ring (Er)
