Table 6 A: GLMM exploring the effects of Internal Relatedness (IR), pairwise relatedness to the female (r), and MHC allele-sharing (D) on the likelihood of being a social or an extra-pair male, B: Relative variable importance given by Akaike weights (ΣAIC ω )

From: Females tend to prefer genetically similar mates in an island population of house sparrows
