1. Identify the type of natural selection illustrated in the graph.

2. List the phenotypes that are fit to survive in the environment.

3. Outline the type of natural selection that is illustrated in the graph.

4. Give a plausible explanation why a specific phenotype will not survive in this environment.

5. Analyze the data in the graph and formulate a conclusion for the data.

6. Evaluate the information provided to you and use the Hardy Weinberg equations to do your
calculation.
[In a population of birds, the allele for wide beaks (B) is dominant to the allele for narrow beaks (b). If 50% the population is heterozygous and 25% is homozygous for narrow beaks, what is the frequency of the allele for wide beaks?
p+q = 1
p? + 2pq + g2 = 1
