Only DMSs that were also significantly associated with a maternal care metric at P < 0.1 are shown in this table, while the remaining fGCM-associated DMSs are in Supplementary Table 8. DNA methylation was assessed during the subadult life stage, and fecal samples were collected from animals during the subadult and adult life stages.
DMSs differentially methylated CpG sites, fGCMs fecal glucocorticoid metabolites, BLUPs best linear unbiased predictors, CHR chromosome.
† Beta estimates and unadjusted P values are from binomial regression models run in program MACAU and then corrected for inflation and bias using the package bacon.
‡ FDR P value based on Benjamini–Hochberg correction (5%).
a Mapping of spotted hyena DNA sequences spanning 20.4k bp onto the human genome (Human Dec. 2013 [GRCh38/hg38] Assembly) was done using the top hit from the UCSC Genome Browser’s BLAT tool.
b Mapping of spotted hyena DNA sequences spanning 20.4k bp onto the domestic cat genome (Felis catus Nov. 2017 [felCat9] Assembly) was done using the top hit from the UCSC Genome Browser’s BLAT tool.
c Reference genome is hg38.
