1 On a nice sunny spring day you decide to go for a walk where you notice a field of flowers There are three colors visible red pink and white You know from you BIO 101 class that this could be the result of incomplete dominance of the red R and white r alleles for the gene encoding flower color a 3 points You decide to do an experiment and count the number of flowers of each color There are 49 red flowers 42 pink flowers and 9 white flowers Assuming that the population of flowers is not currently undergoing microevolution use the Hardy Weinberg equations p q 1 and p 2pq p 1 to determine the frequency of the red and white alleles in the population Show your work b 3 points Next year you continue your experiment and go back to the same field of flowers This time you count 36 red flowers 48 pink flowers and 16 white flowers What are the frequencies of the red and white alleles now Show your work c 2 points Has the field of flowers undergone microevolution Explain how you know this d 3 points Assuming that there is no natural selection pressure on these flowers what other source s of evolution might have acted on the flower population Give an example of what might have
