Song Sparrow (Melospiza melodia graminea) There are populations of song sparrows in various islands off the coast of California. The chart below shows the frequency of the mme allele from each population over the last 10 generations Generation Island 1 0.8 0.7 0.6 0.5 0.4 0.3 0.3 0.3 Island 2 0.7 0.6 0.5 0.4 0.3 0.3 0.3 0.3 0.3 0.3 Island 3 0.6 0.5 0.4 0.3 0.3 Island 4 0.5 0.4 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 Island 5 0.3 0.3 4 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 0.3 10 0.3Draw these four scatterplots: Five populations of Channel Island song sparrows mme allele frequencies over 1 generations . Five populations of water snakes alb allele frequencies over 10 generations Five populations of Aleutian shield fern cyx allele frequencies over Generations 1-10 Five populations of Aleutian shield fern cyx allele frequencies over Generations 427-436 Using complete sentences, answer the following questions regarding the data: 1. 2. 3. 4. Look at the graph of the Channel Island song sparrows. Which migration model is being followed and how do you know this? Look at the graph of the water snakes. Which migration model is being followed and how do you know this? Which organisms (Channel Island song sparrows or the Water snakes) have a faster rate of migration? How do you know this? Look at the Generations 1-10 graph of the Aleutian shield ferns. Which evolutionary force is responsible for the variation in the cyx allele frequencies among the fern populations (drift or migration)? In which populations has the cyx allele reached fixation? What does it mean for an allele to reach fixation? Imagine if the Generations 1-10 Aleutian shield fern population sizes were significantly larger than they actually were. Assuming all other conditions remained the same, how would the increase in population sizes change the timing of each population reaching fixation for one allele? (Describe this change in general terms. You do not need to calculate any specific numbers.) 5.
