Description:

Unexpectedly simpleChinook salmon are known to return to spawn at two distinct times of the year: spring and fall. Individuals that return during these times have generally been referred to as parts of distinct groups, or ecotypes, with traits specific to their timing and presumed divergence being caused by the lack of interbreeding. By looking at genomes across fish from both runs, Thompsonet al.found that a single genomic region of interest was nearly perfectly associated with run timing but not with other traits such as maturity and fat reserves (see the Perspective by McKinney). Further, they conclude that the region operates as a Mendelian trait, with assortment dictating run timing and associated phenotypes being caused by the migration environment rather than genetics.Science, this issue p.609; see also p.526
