Project #69595 - Human genomes

 

Please be brief and concise. 

1. Name two advantages of single polymorphisms (SNPs) over restriction fragment length polymorphisms (RFLPs). 5 points

 

2. Draw a map showing where the following markers are located relative to each other:

Marker pairs     Recombination

Q-N                     10 %

Q-X                      15%

N-X                      5cM

 

3. Where is trait A relative to markers B, F and P? 

Recombination 

A-B                       9%

A-F                       5%

A-P                       3%

B-P                      12%

B-F                       14%

F-P                         2%

 

4. What information do you get from recombination fraction and what information do you get from LOD score?

 

5. Markers D and J show 50% recombination. Where are they located relative to each other?

 

6. What are three ways for an allele to shift frequency in a population?

 

7. How is in vitro fertilization (IVF) performed? 

 

8. What is alpha fetoprotein and how is it used in genetic diagnosis?

 

9. What are the standard forms of prenatal screening and prenatal testing?

 

10. Why would you need to see a medical geneticist?

 

11. What maternal serum proteins can be used to evaluate risk of neural tube defects or aneuploidy in a fetus?

 

12. What is the difference between a test and a screen?

 

13. Neonatal screening asks about traits like phenylketonuria but does not ask about other traits like Huntington disease. Why would you do screening for the one but not the other?

 

14. What are two non-medical uses of genetic testing?

 

15. What risk factors besides tremors might indicate a need to test for Huntington disease repeat expansion?

 

16. What is gene therapy?

 

17. What is adenosine deaminase (ADA) deficiency?

 

18. Who should be involved in a gene therapy trial?

 

19. What are two different therapies strategies for using gene therapy to treat cancer?

 

20. Which trait was the first human trait on which gene therapy is tried, and why was it the trait selected?
