You are a scientist studying the predator-prey relationship between red-tailed hawks (predator) and voles (their primary prey). Red-tailed hawks have two morphs: one morph has a dark underside and the other has a light underside. You hypothesize that color pattern in these hawks is under negative frequency-dependent selection because voles form a search image for commonly encountered predators.
A) State your null and alternative hypotheses.
B) Describe key aspects of your experiment, including your independent (predictor) and dependent (response) variables, and how you will incorporate control and replication.
C) Draw a graph predicting the frequency of each hawk morph in the population (y-axis) over time (x- axis) if the alternative hypothesis is correct and provide an explanation for the shape of your graph.
D) Explain how negative frequency-dependent selection is expected to influence long-term genetic variation in the hawks.
