Which is *not* a condition for successful Batesian mimicry?
Successful Batesian mimicry usually requires the harmless mimic to remain less common than the harmful or unpalatable model. Predators learn the shared warning phenotype by sampling organisms and experiencing the model’s defense. If harmless mimics become too abundant, attacks on that phenotype are rewarded too often, avoidance weakens, and the protective value of resemblance declines through negative frequency-dependent selection. An educated predator is therefore important, because learned association links the model’s appearance with danger. The model normally needs to outnumber the mimic,
