Abstract
For many species, migrating at just the right time is essential for both survival and reproduction. A new study in salmon localizes a small genomic region associated with migration timing, which in turn affects other physiological traits, suggesting that a seemingly complex suite of migration traits is linked by one “simple” phenotype.
