Fig. 4: Enriched Gene Ontology (GO) terms in expanded and unique gene families of the Eurytemora affinis species complex.

a Significantly enriched GO terms among the expanded sets of gene families. b Significantly enriched GO terms among the unique sets of gene families. The GO terms are arranged in ascending order of their P-values (left to right), indicating the strength of their association with the expanded and unique gene sets within each category. These figures include the top 20 GO terms for the Biological Process and Molecular Function categories and the top 15 for the Cellular Component category, with higher P-values towards the right in each category. GO term enrichments were tested using hypergeometric tests (equivalent to one-sided Fisher’s exact tests for over-representation), and P-values were adjusted for multiple comparisons using the Benjamini–Hochberg false discovery rate (FDR) method. All enriched GO terms, including their respective P-values and functional annotations, are listed in Supplementary Data 7 and 9. Source data are provided as a Source Data file.
