These sets were gene ontology terms: “negative regulation of transforming growth factor beta production,” “negative regulation of transforming growth factor beta1 production,” “MHC class I peptide loading complex,” and “TAP complex binding.” We also conducted an ORA to test if a higher proportion of genes from any gene set showed a nominally significant (uncorrected P -value <0.05) association with the life history traits ( supplementary data S5, Supplementary Material online).
