An ecologist, Dr. Rose, is studying a population of field mice that live along a riverbank. After a recent season of heavy rainfall, a flash flood killed the field mice that inhabited dens close to the riverbank, while those that lived more inland survived. It was completely random which field mice lived where, as they have no predisposition to live nearer to vs. further from the water. Dr. Rose is curious whether this population has experienced evolutionary change and decides to test this question via Hardy-Weinberg. Dr. Rose specifically looks at the coat color phenotype, which is coded for by 2 alleles. RR mice express a black coat, rr mice express a tan coat, and Rr mice express an intermediate phenotype of a roan coat with both black hairs and tan hairs. Dr. Rose collects data and finds: 34 black mice, 174 roan mice and 15 tan mice. Given the information provided, which mechanism of evolution does Dr. Rose think likely occurred in this population? [evolution] Given the information provided, what inheritance pattern best describes the genetic control of coat color phenotype? [inheritance]   Calculate the allele frequencies for the population: [allelefrequencies] Calculate the expected genotype frequencies: [ExpectedGenotypes] Calculate the observed genotype frequencies: [ObservedGenotypes]   Based on the data, what is Dr. Rose’s conclusion regarding the evolution of this population? [conclusion]

Dr. Sully is a marine biologist who researches the association between clownfish and two anemone species. Her observations have shown that clownfish are found in both the blue anemone species and the orange anemone species. While the blue and orange anemone species are very similar, the orange anemone species produces a much more toxic venom than the blue anemone species. Clownfish are coated with a mucus layer that protects them from venom of some anemone species, but not all species.Dr. Sully has also observed that there appear to be more clownfish living in the blue anemones than the orange anemones. To test differences in clownfish usage of the different anemone species, she measures the visitation rate of clownfish (# of clownfish visits/hour) to 10 blue anemones and 10 orange anemones. She then compares mean visitation rates between the 2 groups. Which of the following would be the best mechanistic hypothesis for this research?
