Assess students' ability to apply two-species reaction–diffusion models to developmental pattern formation: nondimensionalize a given model (e.g., Schnakenberg or Gierer–Meinhardt), locate homogeneous steady states, perform linear stability analysis to derive the dispersion relation, and determine analytic conditions for Turing (diffusion-driven) instability. Tasks include calculating parameter regimes where the homogeneous state is stable to uniform perturbations but unstable to finite-wavelength modes, finding the most unstable wavenumber and corresponding wavelength, producing stability/parameter-space plots, and interpreting biological implications and sensitivity to diffusion and kinetic parameters.
