This study applies mathematical systems theory to the Fisher selection-mutation model. It shows how mutation rates can control population dynamics to reach a stable, diverse equilibrium.

Area of Science:

  • Evolutionary biology
  • Mathematical systems theory
  • Population genetics

Background:

  • The Fisher selection-mutation model is a cornerstone in population genetics.
  • Understanding population dynamics under selection and mutation is crucial for evolutionary studies.
  • Controllability of biological systems is an emerging area of research.

Purpose of the Study:

  • To analyze the Fisher selection-mutation model using mathematical systems theory.
  • To investigate the role of mutation rates as control functions.
  • To develop a method for achieving population-wide polymorphic equilibrium.

Main Methods:

  • Mathematical systems theory applied to population genetics models.
  • Analysis of non-linear systems with invariant manifolds.
