Abstract

Quantifying sex-specific additive genetic variance (V_A) in fitness, and the cross-sex genetic correlation (r_A), is prerequisite to predicting evolutionary dynamics and the magnitude of sexual conflict. Further, quantifying V_A and r_A in underlying fitness components, and genetic consequences of immigration and resulting gene flow, is required to identify mechanisms that maintain V_A in fitness. However, these key parameters have rarely been estimated in wild populations experiencing natural environmental variation and immigration. We used comprehensive pedigree and life history data from song sparrows (Melospiza melodia) to estimate V_A and r_A in sex-specific fitness and underlying fitness components, and to estimate additive genetic effects of immigrants alongside inbreeding depression. We found evidence of substantial VA in female and male fitness, with a moderate positive cross-sex r_A. There was also substantial V_A in male but not female adult reproductive success, and moderate V_A in juvenile survival but not adult annual survival. Immigrants introduced alleles with negative additive genetic effects on local fitness, potentially reducing population mean fitness through migration load, but alleviating expression of inbreeding depression. Our results show that V_A for fitness can be maintained in the wild, and be broadly concordant between the sexes despite marked sex-specific V_A in reproductive success.
