“…We used Cervus 2.0 to analyze allele frequencies. As noted by Johnson et al (2002), Hru3 has an apparent null allele with an estimated frequency of 0.09 in our population, and the alleles for this locus deviated significantly from Hardy-Weinberg equilibrium. All other loci in this study did not deviate from Hardy-Weinberg equilibrium, and estimated frequencies of null alleles were low ( 0.05).…”

“…Our most prominent finding was that, in pairwise comparisons, EP males that succeeded in siring offspring with a female had fewer common alleles than did other, nearby males that could have sired EP offspring with the focal female but did not (in our population EP sires are typically males on neighboring territories; Johnson et al 2002). This suggested that females may select, either overtly or cryptically, EP sires with rare genotypes.…”

“…Briefly, we obtained DNA samples from within-pair (WP) males, females, offspring, and potential EP sires (i.e., males on adjacent territories; Johnson et al 2002) at 20 nests in Wyoming. We initially typed individuals at five microsatellite loci (Table 1).…”

“…For the current study, we typed individuals at seven additional loci, including Mcyμ4 (Double et al 1997), Ltmr6 (McDonald andPotts 1994), Ase8 (Richardson et al 2000), and TA-B4-2, TA-A5-15, TA-C3(B)-2, and TA-C6-7 (Cabe and Marshall 2001). We conducted all PCR amplifications by the touchdown protocol described in Johnson et al (2002). We used a Beckman Coulter CEQ 8000 capillary sequencer and CEQ software, version 8.0, to size PCR products.…”

“…House wrens are an ideal model species for such a study. Extra-pair mating is common in this species, with 27-40% of broods reported to contain one or more extra-pair offspring, depending on the year and population (Soukup & Thompson 1997;Johnson et al 2002;Poirier et al 2004;Forsman et al 2008). In addition, male house wrens that secure multiple, suitable nest sites on their territories sometimes pair socially with two or more females simultaneously ( Johnson & Kermott 1991a), which further increases the variance in male fitness relative to that of females ( Whittingham & Dunn 2005).…”

Extra-pair young in house wren broods are more likely to be male than female

Sex-allocation theory predicts that females should preferentially produce offspring of the sex with greater fitness potential. In socially monogamous animal species, extra-pair mating often increases the variance in fitness of sons relative to daughters. Thus, in situations where offspring sired by a female's extra-pair mate(s) will typically have greater fitness potential than offspring sired by the within-pair mate, sexallocation theory predicts that females will bias the sex of offspring sired by extra-pair mates towards male. We examined the relationship between offspring sex and paternity over six breeding seasons in an Illinois population of the house wren (Troglodytes aedon), a cavity-nesting songbird. Out of the 2345 nestlings that had both sex and paternity assigned, 350 (15%) were sired by extra-pair males. The sex ratio of extra-pair offspring, 0.534, was significantly greater than the sex ratio of within-pair offspring, 0.492, representing an increase of 8.5 per cent in the proportion of sons produced. To our knowledge, this is the first confirmed report of female birds increasing their production of sons in association with extra-pair fertilization. Our results are consistent with the oft-mentioned hypothesis that females engage in extra-pair mating to increase offspring quality.
