Question 19 (0.1111 points) Using human karyotyping one can find out the following: Number of chromosomes are present in a cell. If any chromosome is missing. If any chromosome is extra. If a part of any chromosome is brocken. All of the above.

Step 1: Define karyotyping — it is the laboratory technique that stains and arranges metaphase chromosomes from a cell into homologous pairs so you can visually examine chromosome number and structure. Show more…

Answer the following questions based on the following karyotype either true or false. Human Karyotype #1 (questions #1-6) 1. There are 46 chromosomes in this karyotype. 2. This a male child. 3. There are multiple trisomies in this individual. 4. This karyotype resulted from nondisjunction of an entire cell. 5. The haploid number of this person is 34 or 35. 6. This individual may have been miscarried. Human Karyotype #2 (Questions #7-12) 7. The diploid number is 46. 8. The haploid number is 23 only. 9. There are 23 homologous pairs of chromosomes. 10. There are no trisomies in this karyotype. 11. The sex is male for this person. 12. This person may experience birth defects.

Lab technicians compile karyotypes and then use a specific notation to characterize the karyotype. This notation includes the total number of chromosomes, the sex chromosomes, and any extra or missing autosomal chromosomes. For example, 47,XY, +18 indicates that the patient has 47 chromosomes, is a male, and has an extra autosomal chromosome 18. 46,XX is a female with a normal number of chromosomes. 47,XXY is a patient with an extra sex chromosome. Al- What notation would you use to characterize Patient A's karyotype? Taking a diagnosis. The next step is to either diagnose or rule out chromosomal abnormality. In patients with a normal number of chromosomes, each pair will have only two chromosomes. Having an extra or missing chromosome usually renders the fetus inviable. In cases where the fetus makes it to term, there are unique clinical features depending on which chromosome is affected. Listed below are some syndromes caused by an abnormal number of chromosomes. 42- What diagnosis would you give Patient A? Diagnosis Chromosomal Abnormality. Normal patients' problems are due to something other than an abnormal number of chromosomes. Klinefelter's Syndrome involves one or more extra sex chromosomes (i.e., XXY). Down's Syndrome is Trisomy 21, an extra chromosome 21. Trisomy 13 Syndrome involves an extra chromosome 13.
