Question

karyotyping activity
patient cs karyotype

1. interpreting the karyotype: what notation would you use to characterize patient cs karyotype?

47, xxy
46, xy
47, xy, +13
47, xx, +18

1. making a diagnosis: what diagnosis would you give patient c?

normal # of chromosomes
klinefelters syndrome
downs syndrome
trisomy 13 syndrome

Explanation:

1. By observing the karyotype image and standard karyotype - notation rules, we count the total number of chromosomes and note the sex - chromosome composition. A normal human has 46 chromosomes. An extra chromosome indicates a trisomy. The notation includes the total number of chromosomes, followed by the sex - chromosome composition and any extra chromosomes.
2. Klinefelter's Syndrome is characterized by the presence of an extra X chromosome in males (47, XXY). Down's Syndrome is trisomy 21 (47, XY, + 21), Trisomy 13 Syndrome is 47, XY, + 13, and a normal male has 46, XY.

Answer:

1. 47, XXY
2. Klinefelter's Syndrome
