Table 4 A: GLMM exploring the effects of brood type (broods with extra-pair chicks vs. broods with no extra-pair chicks) on hatching and fledging success, 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
