“…Among birds, where many species exhibit behavioural systems that suggest monogamous relationships, genetic analyses have often shown that extra-pair fertilizatons (EPFs) occur Westneat 1990;Gowaty & Bridges 1991;Wagner et al 1996). Moreover, both males and females may be responsible for EPFs Birkhead & M0ller 1992;Wagner 1992;Strohbach et al 1998). The benefits to males of engaging in extrapair mating that leads to fertilizing additonal females are reasonably clear.…”

“…Also, the EPY of a brood did not survive better than their half-sibs sired by their social father. Thus, our results could not support the hypothesis that female great tits choose better-quality males for extra-pair matings (Strohbach et al, 1998). All offspring of entire populations of great tits from a period of 4-5 years are currently being screened for relationships employing microsatellite analysis initially.…”

(GATA)_n and additional simple repeated DNA sequences have long been known but functional analyses along traditional research strategies have not yielded definitive results. Therefore these elements are commonly regarded as genomic “junk” although they represent assets for innovative methodological approaches and especially for speculations. While extensively using microsatellites for genome mapping and genetic relationship analyses, it was also realized that certain simple repeats can cause human trinucleotide block expansion diseases. Hence these simple repeat elements comprise an exceptional range of biological meaning, i.e. from genetically absolutely neutral markers for genome analysis, behavioral and population genetic studies to dominant and invariably disease causing mutations with complete penetrance. The quest into why there is so much repetitive junk in recent genomes can be answered only in part and sequentially, but sometimes – even after substantial efforts – not for the given element.

“…Oct, 2001) we analysed the role of male paternity guarding strategies in situations where females seek EPF for reasons of genetic compatibility and/or in pursuit of genetic diversity (bet hedging) for their offspring [cf. Strohbach et al (1998), Krokene et al (1998) and Kempenaers et al (1999)]. In situations where the use of the paternity assurance strategies is unfeasible, males face the possibility of investing paternal care in unrelated young.…”

Fertility Assurance Through Extrapair Fertilization, and Male Parental Effort

Extrapair paternity (EPP) has been observed in many formally monogamous species. Male pursuit of extrapair fertilizations (EPF) is explained by the advantages of having offspring that receive essential paternal care from other males. Because females are capable of exercising a degree of control over the post-copulatory sperm competition, EPP's persistence indicates that females benefit from EPF. Thus, EPP involves cooperation between mated females and extrapair males. On the other hand, mated males exhibit a spectrum of anti-cuckolding strategies. Hence, extrapair attributes of diverse species and populations reported in the literature are particular solutions of evolutionary games involving gender-specific cuckolding/anti-cuckolding strategies. Here we use game theoretical methods to study the effect of male paternal effort conserving strategies in situations where females seek EPF for reasons of genetic compatibility and/or in pursuit of genetic diversity for their offspring. Our results indicate that in these circumstances pursuit of EPF is the only evolutionary stable female strategy. Males, on the other hand, have two, mutually exclusive, evolutionary stable strategies: males that restrict parental care regardless of their mate's fidelity, and males that never restrict parental care. That is, when females seek EPF for reasons of fertility assurance and/or genetic diversity, the conditional male strategy--therein the male's parental efforts are based on his certainty of paternity--loses in competition with the unconditional strategies.
