Genotype and extra-pair paternity in the house wren: a rare-male effect?

Proceedings. Biological sciences - 7 Jul 2003

Masters Brian S, Hicks Bonnie G, Johnson L Scott, Erb Lori A

Abstract excerpt

Females in socially monogamous species may select extra-pair (EP) mates to increase the heterozygosity, and hence fitness, of their offspring. We tested this hypothesis in the house wren (Troglodytes aedon), a largely monogamous songbird in which EP young are common. We typed paired males and females, nestlings, and males on neighbouring territories, at five to seven microsatellite loci over 2 years in a Wyoming,...
