However, this assumes the
simplest scenario, where all individuals in the mimicry
complex have the same toxicity for all potential predators.
If the situation is one in which there are di¡erences in toxicity
between models, and, more complex still, di¡erences
between predators in their sensitivities to the toxic properties
of di¡erent mimics, then the strength of purifying
selection will be reduced, potentially allowing multiple
MÏllerian mimicry to develop.
