The genetic basis of dispersal in a vertebrate metapopulation

Dispersal affects evolutionary processes by changing population size and genetic composition, influencing the viability and persistence of populations. Investigating which mechanisms underlie variation in dispersal phenotypes and whether populations harbor adaptive potential for dispersal is crucial to understanding the eco-evolutionary dynamics of this important trait. Here, we investigate the genetic architecture of dispersal among successfully recruited individuals in an insular metapopulation of house sparrows. We use an extensive long-term individual-based ecological data set and high-density single nucleotide polymorphism (SNP) genotypes for over 2500 individuals. We conducted a genome-wide association study (GWAS), finding a relationship between dispersal probability and an SNP located near genes known to regulate circadian rhythmic, glycogenesis and exercise performance, among other functions. However, this SNP only explained 3.8% of variance, suggesting that dispersal is a poly..., , , # Data from: The genetic basis of dispersal in a vertebrate metapopulation

## Description of the data and file structure

The following datasets are included:

**SNPpedigree_GeneticArchitecture.txt:** A metapopulation-level pedigree that was constructed based on parentage analyses using individual high-density SNP-genotype data in the R-package sequoia (Huisman, 2007; Niskanen et al., 2020). Individual, dam and sire IDs can be found in this file. Any missing parents (i.e. sire and dam) are encoded as “NA” in the pedigree. The \"Real.Individual\" column indicates whether the individual is a real individual (\"1\") or a dummy individual (\"0\").

**GGAM_data_GeneticArchitecture.txt:** Data used in the genetic ...
