Question 3: Pikas are small mammals that live at high elevation in the talus slopes of mountains. Most populations located on mountaintops in Colorado and Montana in North America are isolated from one another: the pikas don't occupy the low-elevation habitats that separate the mountain tops and don't venture far from the talus slopes. Thus, there is little gene flow between populations. Furthermore, each population is small in size and was founded by a small number of pikas. A group of population geneticists propose to study the amount of genetic variation in a series of pika populations and to compare the allelic frequencies in different populations. Based on the biology and distribution of pikas, make qualitative predictions of what the population geneticists will find concerning: 1 the values of Fst 2_indicators of within-population genetic variation (please mention what measures you are considering to asses within-population variation) (NOTE: this is a conceptual question and not really a numerical problem, answers like, high/ low, OR a lot/a little are perfectly fine).
