Correlation analyses of maternal mRNA abundance of candidate target genes across the haplochromine species used in this study. a Pearson correlation coefficient (r) was used to assess the similarity between differences in mRNA abundance of the target genes and egg weights across all species. b Pearson correlation coefficient (r) analyses, assessing the pairwise expression similarity between the candidate target genes. c A dendrogram clustering species based on expression pattern similarities of the candidate target genes, when combined together. The species are represented by the same symbols used in Fig. 1a
