[Questions 52-55] The figure shows the Samoa islands in the Pacific Ocean and the size of each island. The distance of the island chain from other land masses is shown in the figure. To Swain Island To Hawaii 2600m, 4700km 200ml, 320km Island Area (square miles) Samoa Islands Savai'i 654 434 SAVAI'L Uplou Tutuila SAMOA 55 AMERICAN SAMOA Ta'u 17 Apla UPLOU Ofu ta'u Olosega TUTUILA Aunu'u To New Zealand 1800ml, 2800km 100 kilometers 100 Miles Imagine that a species of grasshopper has a large population that was found spread throughout the island of Savai'i. In the grasshopper population found on Savai'i, there is a specific locus in the genome that is a VNTR region, and there are 20 alleles found at this VNTR locus. Initially, this species was only on Savai'i and was not found on the other islands. Then the following occurs: 1. A small group of dispersers left Savai'i and colonized Uplou 200,000 years ago. 2. After 100,000 years on Uplou, a small group of dispersers leaves Uplou and colonizes Tutuila. 3. After ten years on Tutuila, half the population on Tutuila leaves and colonizes Ta'u, 4. individuals move freely between the populations on Savai'i and Uplou. We would expect genetic diversity for the VNTR locus of the grasshopper to be higher on Savai'i than on Uplou. O a. True O b. False The grasshopper population on Tutuila is more likely to go extinct than the population on Uplou. O a. True O b. b. False Species diversity on Uplou and Tutuila will be similar. O a. True O b. False Uplou is more likely to receive immigrants from Fiji than Australia. O a. a. True O b. False Apolima h Manono To Australia 2500m, 4000km To Fiji 800ml. ✔1200km To Tahiti 1500ml, 2400km Rose Atoll
