2) A population of terrestrial snails lives on a continent; while most of the individuals in the population have an allele to make them nocturnal, some have an allele that makes them diurnal (active primarily during the day). A huge storm comes along and causes some snails (number and type unspecified) to be washed out to sea from the continent, eventually ending up on an island that previously has had no snails (but has food for the snails).
The island hasn't been studied much, but it's known that two species of predators that can feed on snails exist on the island: one species is active during the day, and one active during the night. Little else is known about the predators' abundance or skill at hunting snails.
What might happen to the prevalence of the diurnal allele in the island population of snails over time?
12a) If there are multiple possible outcomes, explain at least three
12b) Clearly illustrate what could cause the different outcomes
12c) List any assumptions you need to make.
12d) Demonstrate your knowledge of evolution and all its mechanisms when discussing the possible outcomes. If a mechanism of evolution might possibly come into play, be sure to discuss it somewhere.
12e) Use key terms (Genetic drift, allele frequencies, natural selection, population bottlenecks, fitness, adaptation, and artificial selection) and underline key points. (You do not have to use all of the terms)
