Clustering of genes by sequential stages of development. Genes expressed from PN to BL were analyzed for co-expression using the SOTA clustering (x-axis labels: 1 = PN, 2 = 2C, 3 = 4C, 4 = 8C, 5 = MO, 6 = BL). Clusters were assigned an expression profile based on fluctuations between stages: decreasing after 8C (5 clusters; red), 8C elevated (1 cluster; orange), EGA (3 clusters; green), MO and BL elevated (1 cluster; cyan), MO elevated (3 clusters; navy), decreasing post-EGA (1 cluster; purple), and neutral (2 clusters; grey).
