Abstract excerpt
Intrapopulation variation in the age at return and reproduction of Chinook Salmon (Oncorhynchus tshawytscha), or age-at-maturity, acts as a buffer against stochastic environmental variation. We investigated the genetic component of this trait by estimating the heritability of age-at-maturity and the genomic basis of both sex and age-at-maturity in stocks representing the 3 major lineages of the Columbia River...
