1 INTRODUCTION There are many advantages to establishing dominance over conspecifics, such as increased monopolisation of resources (Kaufmann, 1983; Tibbetts et al., 2022), improved feeding opportunities (Hahn & Bauer, 2008; Ward et al., 2006) and greater reproductive success (Ellis, 1995; Pusey et al., 1997). The outcome of a given dominance contest is often determined by the level of aggression exhibited by each opponent (Kaufmann, 1983).
Abstract Large effects loci often contain genes with critical developmental functions with potentially broad effects across life-stages. However, the life-stage-specific fitness consequences are rarely explored. In Atlantic salmon, variation in two large-effect loci, six6 and vgll3 , is linked to age at maturity, and several physiological and behavioural traits in early life.
Abstract Genomic regions with large phenotypic effects often contain genes that may have critical roles as early as development, with potentially broad physiological and morphological effects across later life stages. However, the life-stage-specific fitness consequences are rarely explored.
