Generalized linear mixed models correlating 3 fitness proxies (YR = years as reproducers, LSY = litter size per year, TO = total offspring) to relatedness (r) and heterozygosity (Ho) of the breeding pair members at the 12 microsatellites and 3 MHC loci

AIC, Akaike’s Information Criterion; df, degrees of freedom.

Significance “**” = 0.01 and “*” = 0.05.
