Same prompt, different question: Suppose you are a researcher studying a population of beach mice living in the coastal dunes of Florida. You notice that, although there is some variation in coat color, most of the mice have fairly light fur, which appears to help them blend into the sandy dunes. 1) After several experiments, you determine that mice with extremely light or very dark coat colors are more easily detected by predators, and you conclude that mice with those coat colors normally have lower fitness. 2) You are given permission to try to establish a new colony of beach mice at a nearby, protected beach. You capture 15 mice and transfer them to the protected beach. However, by chance, the mice you captured have a higher proportion of dark-colored coats than the original population did. 3) The dunes on the new beach are a darker color than the original beach, which allows the dark mice to survive better than the light-colored mice. After a few years, you determine that your population of beach mice is expanding rapidly, and that they have a higher proportion of alleles for dark coat color than the original population did. 4) After the population has been established for more than a decade, the storm surge from a hurricane kills the majority of the population, although the population is eventually able to rebound. Which numbered stage(s) in this scenario illustrates a bottleneck effect? Group of answer choices 1 only 3 only 4 only 2 only
