Lion Geography Microsat Activity

Lion Geography and Microsatellite Activity Now that you have found your lion population, we need to find where you are geographically located. Each population has a set of GPS coordinates for the location of the pride. Using Google Maps, type in the coordinates provided for your population into the search bar. You will need to zoom out in order to find the country in which each population is located. (See below) Once you locate your population, you will plot it on the attached map of Africa. On the map of Africa below, locate and write the number of your pride in the country where it appears. Then, write where your pride is on the map projected on the board. As each group finishes, copy where the prides are located on to your map. GPS Coordinate Data 1. Cameroon – 7.3697 N, 12.3547 E 2. Tsavo – 2.1833 S, 38.4167 E 3. Fannie Roberts – 26.5225° S, 31.4659° E 4. Sabi Sands – 24.788 S, 31.4914 E 5. Umfolozi – 28.3430 S, 31.9743 E 6. Zimbabwe – 19.0154 S, 29.1549 E 7. Zambia – 13.1339 S, 27.8493 E 1 8. Kalahari – 25.5920 S, 21.0937 E 2 9. Botswana – 22.3285 S, 24.6849 E 10. Etosha – 18.8556 S, 16.3293 E 7 6 9 4 8 3 5 Analyzing Microsatellite Data You were initially given a “bar” that represented a set of alleles carried by a lion within a population. We now know that lion populations share many family members and, therefore, more similar alleles. But how do the alleles of different populations compare to one another? 1. What lion prides would you guess to be most closely related based on the map? 3 and 4 because they are super close so it’s the least difference and lions don’t want to walk a long time. 2. What lion prides would you guess to be most distantly related based on the map? 1 and 5 because they are the farthest from each other. 3. Write two (2) populations that have very similar alleles. Botswana and Zimbabwe Why did you choose these two populations? - Because on the map they are right next to each other - also, they have very similar colors on the chart. 4. How do the two populations you chose above compare to one another geographically? - They are pretty in different countries, but they are close. 5. Based on geography, give one population you would expect to be very genetically different than many of the other populations. Why did you choose this population? - Cameroon I would except to be different because they are all the way up in the middle of Africa and the others are in south Africa. 6. With which other population does the Fannie Roberts population seem to share many of its alleles? Zambia because they share lots of red. Why is that finding unusual based on your understanding of the lion geography? Because they are far from each other. 7. In Zambia, which 4 lions are likely to have migrated from a different population? 208, 209, 210,211 From which population do you believe they may have originated? Kalahari How does the geography of these two populations support or refute that finding? They are close enough that they could have migrated. 8. Using evidence from your map, explain why the alleles in the Cameroon population are different from all the other lion populations. Because they are in the middle of Africa and the rest of tribes/ prides are in south Africa. 9. The Etosha population is located in a National Park. Explain why the lions in this population may be genetically similar. (Consider how a population in a park is different than a wild population.) They’re less lions to mate with therefore they must mate with the same or similar people. 10.In your own words, explain how geography influences genetics. The closer you are to someone the more chances you have to be related to them because you don’t have to migrate as far.
