MHC-associated variation in sexual swelling components and body condition. (A) A fully-swollen female baboon mate-guarded by an adult male. (B) Effect of six MHC supertypes on swelling components and body condition (note that the results relative to MHC supertype S11 are not displayed because S11 is systematically possessed in association with S2 - see Table S1, Additional File 1). Means and standard errors are shown. The variation in swelling area or swelling shape estimator is illustrated on the relevant axis.
