Table 1 Results of the full model (n = 41 males) showing effect of scaled body condition, ornamentation and number of MHCIIB amino acid variants on male pairing status

From: Mate choice for major histocompatibility complex complementarity in a strictly monogamous bird, the grey partridge (Perdix perdix)
