WebThe phenotypic gambit Simplifying assumption that complex traits, such as behavioural traits, can be modelled as if they were controlled by a single distinct allele, meaning that we Can focus exclusively on he phenotype, analysing how selection acts on phenotypic variation to influence fitness. WebThe phenotypic gambit is a powerful idea and it has yielded some productive work in behavioral ecology. I use it. However, a complete evolutionary explanation of a trait's existence needs to consider all levels of explanation.
