Question

question 6
what would be the correct notation to characterize patient cs karyotype?
a 46, xy
b 47, xy, +18
c 47, xy, +13
d 47, xxy
e 47, xy, +21
question 7
what disease or disorder would you say patient c has?
a turners syndrome
b patau syndrome
c edwards syndrome
d klinefelters syndrome
e downs syndrome

Explanation:

In karyotype notation, the first number indicates the total number of chromosomes. A normal human has 46 chromosomes. An extra chromosome leads to a total of 47. Different syndromes are associated with extra copies of specific chromosomes. Edward's Syndrome is caused by an extra copy of chromosome 18 (47, XY, +18), Patau Syndrome by an extra chromosome 13 (47, XY, +13), Klinefelter's Syndrome by an extra X - chromosome in males (47, XXY), Down's Syndrome by an extra chromosome 21 (47, XY, +21), and Turner's Syndrome is characterized by a single X - chromosome in females (45, X). Without additional context, if we assume a common trisomy - related disorder, Down's Syndrome (47, XY, +21) is a well - known one. For the disease associated with the karyotype, Down's Syndrome is caused by trisomy 21.

Answer:

Question 6: E. 47, XY, +21
Question 7: E. Downs Syndrome
