“…Previous studies carried out on this species found significant heterozygosity–fitness correlations considering different life‐history traits (reproductive performance: Foerster, Delhey, Johnsen, Lifjeld, & Kempenaers, 2003; García‐Navas, Ortego, & Sanz, 2009; Olano‐Marin, Mueller, & Kempenaers, 2011b; survival probability: Olano‐Marin, Mueller, & Kempenaers, 2011a; and parasite resistance: Ferrer, García‐Navas, Sanz, & Ortego, 2014). Consanguineous matings have been reported in these populations (Ferrer et al., 2014; García‐Navas et al., 2009), which may increase variance in inbreeding and the chance of detecting HFC due to extensive ID across the genome (Balloux et al., 2004; Szulkin et al., 2010).…”
