Genographic Classmates

Hey All,

Great discussion in the classes today - please make sure that you understand why and how the Genographic Project traces one's father's lineage using DNA on the Y chromosome, and the mother's using mitochondrial DNA (mtDNA). To brush up on this, go to www.national geographic.com/genographic and click on "genetics overview."

We will be reviewing for Thursday's test (see the previous post) tomorrow and Wednesday. Please bring clarifying questions for your Tuesday or Wednesday science workshop.

Also for Tuesday or Wednesday, you are reading the genographic results for either, A.T., N.K., or A. M-S. (initials to protect the innocent).

For your classmate, please answer the following:
1. Whose results have you read?
2. Was this student's mother's or father's lineage tested?
3. How can you tell in question #2?
4. What happened in Africa 50,000 years ago that resulted in migration?
5. According to the results, what was the pathway that your classmate's ancestors followed?
6. Do these results seem to make sense? WHY or WHY NOT?

Remember, be descriptive and analytical - you are scientists!
