Patterns of gene expression in ovaries of dominant and subordinate wasps. A summary of the ovary microarray data, for 2302 differentially regulated transcripts across the five groups (DF = dominant foundress, SF = subordinate foundress, DW = dominant worker, SW = subordinate worker, Q = queen). A) Consensus clustering analysis (from both principal components analysis and hierarchical clustering) shows that many transcripts showed a pattern that corresponds to gross ovary activation state. Wasp ovary drawings adapted from [39]. B) Venn diagrams summarizing the number of differentially regulated transcripts associated with either dominance status (top) or caste (bottom) and showing the overlaps between contrasts used to identify 'ovary dominance-associated' transcripts (top) and 'ovary caste-associated' transcripts (bottom).
