Understanding the genetic basis of traits involved in adaptation is a
major challenge in evolutionary biology but remains poorly understood.
Here, we use genome-wide association mapping using a custom 50 k single
nucleotide polymorphism (SNP) array in a natural population of collared
flycatchers to examine the genetic basis of clutch size, an important
life-history trait in many animal species. We found evidence for an
association on chromosome 18 where one SNP significant at the genome-wide
level explained 3.9% of the phenotypic variance. We also detected two
suggestive quantitative trait loci (QTLs) on chromosomes 9 and 26. Fitness
differences among genotypes were generally weak and not significant,
although there was some indication of a sex-by-genotype interaction for
lifetime reproductive success at the suggestive QTL on chromosome 26. This
implies that sexual antagonism may play a role in maintaining genetic
variation at this QTL. Our findings provide candidate regions for a
classic avian life-history trait that will be useful for future studies
examining the molecular and cellular function of, as well as evolutionary
mechanisms operating at, these loci.
