An ecоlоgist, Dr. Rоse, is studying а populаtion of field mice thаt 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]
