Table S5. Effects of genetic similarity on female fertility (pregnant yes/no), based on numbers of shared MHC antigens instead of the dichotomous sharing/no sharing and restricting the analyses to only warmblood mares (N=173). from Major histocompatibility complex-linked social signalling affects female fertility

Likelihood ratio tests comparing GLMMs and GLMs with genetic markers (fixed factors) and/or stallion identity (“ID”, random factor) and reference models (indicated in italics) to test the effects of (A) number of shared MHC antigens (“MHC”, range 0 to 3), and (B) the effects of the number of shared MHC antigens and r in the subsample of 113 mares that allow for a direct comparison. Significant p-values are emphasized in bold
