Log on to: http://www.biology.arizona.edu/Human_Bio/activities/karyotyping/karyotyping.html Answer the following questions. 1. How many karyotypes are performed a year in the United States and Canada? 40,000 2.

a. When are the 23 pairs of chromosomes visible? During mitosis b. With this in mind, when can a karyotype of a cell ONLY be done?

3. What type of dye stains the chromosomes?

Giemsa

4. What are the 2 bases that the dye stains? Adenine and Thymine 5. What are the 3 aspects of a chromosome you must look at to match the homologous chromosomes together? a. b. c. Click on “Patient Histories” Answer the following questions. 6. Who is patient A? fetus chromosomes obtained from fetal epithelial /// 40 year old felmale 8. Who is patient B? infertile 28 year old male 9. Why is he getting a karyotype? 10. How were the chromosomes obtained from Patient B? 11. What occurred to Patient C after birth? Died soon after birth 12. What type of abnormalities were present in Patient C? cleft lip Scroll to the bottom of the page and click on “Patient A”. Match up the chromosome to the left of the paragraph to its homologous chromosome shown in the chart. Look at the chromosome to the left and click on one of the blue blanks with half of a homologous pair in the karyotype that the chromosome would match up with. If the match is incorrect, the website will let you know and will give you another chance to match it up. When you are finished, use the next screen to answer the following questions. The karyotype you completed is at the bottom of the screen. 13. What is the sex of patient A? felmale 14. At which spot (chromosome #) in the karyotype does this person have an extra chromosome? 21 15. Read through the paragraph on karyotype notation. What notation would you use to characterize Patient A’s karyotype? 16. Read through the paragraph on the types of chromosomal disorder. What diagnosis would you give Patient A? down syndrome 17. Is this disorder due to monosomy or trisomy? What does trisomy mean? monosomy? Scroll to the bottom of the page and click on “Patient B”. Follow the same instructions for Patient A’s karyotype. 18. What is the sex of patient B? male 19. At which spot (chromosome #) in the karyotype does this person have an extra chromosome? 13 20. What notation would you use to characterize Patient B’s karyotype?

21. What diagnosis would you give Patient B? kline felter syndrome 22. Why is patient B infertile? Scroll to the bottom of the page and click on “Patient C”. Follow the same instructions for Patient A’s karyotype. 23. What is the sex of patient C? male 24. At which spot (chromosome #) in the karyotype does this person have an extra chromosome?

25. What notation would you use to characterize Patient C’s karyotype? 26. What diagnosis would you give Patient C? trisomy or down syndrome 27. What are the symptoms of this particular disorder? Karyotype 1

28.

Karyotype 2

a. What type of chromosomal disorder is shown in karyotype 1? b. This is also known as Trisomy _. Why?

29. What is the sex of the person who created karyotype 1? 30. Which patient A, B or C) is represented by karyotype 1? 31. What type of chromosomal disorder is shown in karyotype 2? 32. What is the sex of the person who created karyotype 2? 33. Which patient (A, B or C) is represented by karyotype 2? 34. Which karyotype is represented with 47, XXY? 35. Which karyotype is represented with 47, XX +21? 36. What would be the notation for a person who has Triple X? _ 37. What would be the notion for a person who has Turner’s Syndrome?
