Mode of inheritance underlying expression divergence in eggs within a single species. A 8,722 genes are categorized as “conserved” (no expression level difference among parental or offspring’s eggs). B 523 of the remaining 1,155 genes that are differentially expressed between PP and LL eggs have been classified by their primary mode of inheritance. 102 genes are found to be differentially expressed between PL and LP. C A heatmap of genes with statistical support for parental effect direction. Relative gene expression is shown, with colors scaled per-gene. The expression direction (red is high expression and blue is low expression) for these genes matches the direction of either parental type. For example, if PP and PL have the same direction of expression (same color) this is a maternal effect, whereas if PL matches the direction of LL it is a paternal effect on expression. 24 genes are classified as primarily paternally inherited, and 17 as maternally inherited
