The relationship between genetic diversity and fitness, a major issue in evolutionary and conservation biology, is expected
to be stronger in traits affected by many loci and those directly influencing fitness. Here we explore the influence of
heterozygosity measured at 15 neutral markers on individual survival, one of the most important parameters determining
individual fitness. We followed individual survival up to recruitment and during subsequent adult life of 863 fledgling pied
flycatchers born in two consecutive breeding seasons. Mark-recapture analyses showed that individual heterozygosity did
not influence juvenile or adult survival. In contrast, the genetic relatedness of parents was negatively associated with the
offspring’s survival during the adult life, but this effect was not apparent in the juvenile (from fledgling to recruitment)
stage. Stochastic factors experienced during the first year of life in this long-distance migratory species may have swamped
a relationship between heterozygosity and survival up to recruitment
