The next five questions (questions 11-15) are related to each other. Read all of the scenarios very carefully and in order and select the correct answer. A population of 10,000 blue grasshoppers lives on an island. Most members of the population live among the grasses because they are not very good climbers. Some grasshoppers live in the trees because they are good climbers. One year, a short-legged mouse arrived at the island and ate all grasshoppers within its reach, thus totally wiping out the grasshoppers living in the grasses. Luckily, those grasshoppers that were good climbers were spared. This story is an example of Gene Flow Founder Effect C Natural Selection Genetic Drift

**Question**: Twenty living grasshoppers floated on a log to a nearby island just before the "Great Mouse Attack." They joined the population of grasshoppers already living on that island. What is the best explanation for the type of microevolutionary process that this represents? - **A) Gene Flow** - **B) Bottleneck Effect** - **C) Natural Selection** - **D) Founder Effect** **Explanation**: The scenario describes a situation where a small number of grasshoppers are transported to a new location and integrate with the existing population. Among the choices: - **Gene Flow** refers to the transfer of genetic material between separate populations. - **Bottleneck Effect** occurs when a population's size is drastically reduced for at least one generation. - **Natural Selection** is the differential survival and reproduction of individuals due to differences in phenotype. - **Founder Effect** involves a small group of individuals establishing a new population, leading to changes in allele frequencies. In this situation, the most appropriate explanation is **Gene Flow** (Option A), as the new grasshoppers introduce their genes into the island's existing population, influencing genetic diversity.
