Research Ancestry DNA Kits

There are many avenues to testing your ancestry through DNA Kits. Find a website that offers the testing and answer the following question.

1) Which DNA testing site did you research?

2) What is the process to submitting your DNA and how long until you hear back?

3) Does the company address the privacy and protection of the DNA submitted?

4) Are there any medical tests done on the DNA supplied or just lineage?

5) Is there any indication as to how many DNA markers they use to trace your ancestry?

6) Do they look at Y-chromosome, mitochondrial DNA and/or autosomal chromosomes?

7) How far back does the kit trace (in years)?

8) What ethnic regions are covered by the test?

9) Does the site offer further resources to contacting relatives that were discovered during the testing?

10) If you have submitted a kit before tell me about your results and what surprised you?

Each answer should be about 150-200 words

1. Is there enough evidence that indicates that culture buffers humans from a lot of selective pressures that killed off our ancestors? What are some examples in the way humans have done so.

2. What are some examples of artificial and natural selection that weren’t discussed in this chapter? Give examples of what traits have been selected for? For natural selection, what was the selective agent?

3. If humans evolved from monkeys, why do monkeys still exist?

4. Recently, strains of bacteria have become resistant to antibiotics. Based on the chapter, explain how the overuse of antibiotics could influence evolution of bacterial diseases.
