Final answer:
Müllerian mimicry is seen when unrelated but toxic organisms resemble each other, benefiting from shared warning coloration that deters predators.
Step-by-step explanation:
When unrelated but toxic organisms resemble each other, we are seeing an example of Müllerian mimicry. This form of mimicry involves multiple species that both produce toxins and display similar warning coloration. Each of these toxic species benefits from the shared warning coloration because predators learn to avoid them all, reducing the likelihood of any individual from these species being attacked and eaten.
Batesian mimicry, on the other hand, occurs when a harmless species mimics the coloration of a toxic species, benefiting from the predators' aversion to the toxic model organism. This offers protective advantage to the mimic species, which does not have the same defenses as the toxic organism it resembles.
