Table 2.
Sources of variation in mate preference in the sequential experiment for (a) the overall dataset (nmales=27) and (b) the Swedish population only (nmales=19). (AIC value was used to select the best model, with smaller AIC indicating a better-fit model. The difference between the two AIC values was considered insignificant when equal to or less than 1.)

Alternative MHC similarity measures, MHC class I alleles shared, MHC class II alleles shared, MHC major alleles shared, MHC major I alleles shared and MHC major II alleles shared did not significantly predict mate preference in the sequential experimental.
