Question

why is understanding genetic diversity crucial in medical research?
a. doesnt impact medical research
b. creates limitations in treatments
c. helps understand how diseases manifest differently and develop tailored treatments
d. hinders scientific progress

which genetic disorder primarily affects individuals of african descent due to a point mutation?
a. sickle cell anemia
b. down syndrome
c. klinefelter syndrome
d. tay - sachs disease

how does klinefelter syndrome differ from typical male chromosomes?
a. it lacks an x chromosome
b. it has an extra x chromosome (xxy)
c. it lacks a y chromosome
d. it has an extra y chromosome

what causes tay - sachs disease?
a. mutations in the hexa gene
b. inversions in chromosome 5
c. translocations between chromosome 13 and 20
d. an extra copy of chromosome 21

Explanation:

• First question: Genetic diversity helps in understanding disease manifestations and tailoring treatments. Options a, b, d are incorrect as genetic diversity is crucial (not unimpactful, not creating limitations in a negative way for progress, not hindering).
• Second question: Sickle Cell Anemia is a genetic disorder with a point mutation mainly affecting those of African descent. Down syndrome is due to an extra chromosome (trisomy 21), Klinefelter is XXY, Tay - Sachs is due to HEXA gene mutations (not relevant here).
• Third question: Klinefelter syndrome has an extra X chromosome (XXY) compared to typical male (XY).
• Fourth question: Tay - Sachs is caused by mutations in the HEXA gene. Inversions in chromosome 5 (not related), translocations (not relevant), extra copy of chromosome 21 is Down syndrome.

Answer:

1. C. Helps understand how diseases manifest differently and develop tailored treatments
2. A. Sickle Cell Anemia
3. B. It has an extra X chromosome (XXY)
4. A. Mutations in the HEXA gene
