dc.description.abstractRainbow trout (Oncorhynchus mykiss) exhibit partial migration, and are well-suited to studying the genetic basis of migration due to phenotypic differences between residents and migrants. We used data from a common garden experiment to identify SNPs associated with migration in the F1 generation of two familial crosses. We genotyped 192 individuals at 57,501 known polymorphic positions across the genome, and performed sliding window analyses for various metrics to identify regions of the genome potentially under selection. We identified 4,994 and 436 significant SNPs in each of our families, suggesting that life history is controlled via a complex, polygenic pattern of inheritance. Within one family, we located significant markers associated with 29 genes with functions connected to smoltification-related pathways. Chromosome 5 stood out across sliding window analyses, indicating that this region is under selection. We also developed a model to predict life history, which we hope will have conservation implications.en_US
