Fluctuating selection models are supported by theoretical and empirical frameworks as a valid mechanism for maintaining genetic polymorphisms across various ecological conditions.

The analysis

Both retrieved papers (0 and 1) explicitly model and support the role of fluctuating selection in maintaining genetic polymorphisms, detailing specific mechanisms such as storage effects and temporal variation. Paper 2 discusses inversion polymorphism and balancing selection generally but does not refute fluctuating selection models. Therefore, the claim is supported.

Jason Bertram, Joanna Masel. Different mechanisms drive the maintenance of polymorphism at loci subject to strong versus weak fluctuating selection. 2017. https://doi.org/10.1101/164723

The study models seasonally variable selection and highlights mechanisms like ecological storage and dominance reversal that maintain genetic polymorphism under fluctuating selection.
