Not every ecosystem has large areas of similar vegetation, as the habitats in your study do. In areas where patches of more visually varied habitats exist, individual snails regularly move into and out of different visual surroundings. For snails in this situation, having or not having bands does not necessarily offer any protection by camouflage. In fact, in these cases, predators may learn to spot the most common phenotype and selectively feed on those snails. Suppose you released another 100 snails in a more varied habitat, with the numbers of each phenotype shown in the blue circles. Which phenotype would you expect birds to begin to recognizing as food? How might this affect the allele frequencies of the banding gene over time?
