Genomic region associated with run timing has similar haplotypes and phenotypic effects across three lineages of Chinook salmon.

ABSTRACT: Conserving life-history variation is a stated goal of many management programs, but the most effective means by which to accomplish this are often far from clear. Early- and late-migrating forms of Chinook salmon (Oncorhynchus tshawytscha) face unequal pressure from natural and anthropogenic forces that may alter the impacts of genetic variation underlying heritable migration timing. Genomic regions of chromosome 28 are known to be strongly associated with migration variation in adult Chinook salmon, but it remains unclear whether there is consistent association among diverse lineages and populations in large basins such as the Columbia River. With high-throughput genotyping (GT-seq) and phenotyping methods, we examined the association of genetic variation in 28 markers (spanning
