Understanding the genetic architecture of quantitative traits can provide insights into the mechanisms driving phenotypic evolution. Bill morphology is an ecologically important and phenotypically variable trait, which is highly heritable and closely linked to individual fitness. Thus, bill morphology traits are suitable candidates for gene mapping analyses. Previous studies have revealed several genes that may influence bill morphology, but the similarity of gene and allele effects between species and populations is unknown. Here, we develop a custom 200K SNP array and use it to examine the genetic basis of bill morphology in 1857 house sparrow individuals from a large-scale, island metapopulation off the coast of Northern Norway. We found high genomic heritabilities for bill depth and length, which were comparable with previous pedigree estimates. Candidate gene and genome wide association analyses yielded six significant loci, four of which have previously been associated with craniofacial development. ... : All phenotypic measurements for Helgeland house sparrowsFile containing all phenotypic measurements for Helgeland individuals used in main analysis (metapopulation location 66°30’N, 12°30’E). Measurements were taken from all adult birds recorded between 1998-2013. id is individual id as determined by ring number. Sex is the genetic sex. Hatch island is the island the bird was first recorded on. Hatch year is the first year recorded if a bird was measured as a nestling, or the year prior to first year recorded if first measured as an adult. Year and month refer to the date the phenotypic measurement was taken. Age is the age of the bird when the measurement was taken. Island is the same as hatch island if hatch island is one of the 8 SNP-typed islands, else the island is that on which the blood sample for SNP typing was taken.LundreganEtAl_PhenosAll.txtSingle phenotypic measurements for Helgeland house sparrows adjusted to May 2CYFile containing single phenotypic measurements for Helgeland individuals used in ...
