Question

the most common fatal genetic disorder of caucasians is
multiple choice
hemophilia.
cystic fibrosis.
sickle cell anemia.
cholera.
muscular dystrophy.

Explanation:

Cystic fibrosis is a recessive genetic disorder caused by mutations in the CFTR gene. It is most prevalent in Caucasian populations, with a carrier frequency of about 1 in 25, making it the most common fatal genetic disorder in this group. Hemophilia is less common, sickle cell anemia affects primarily African populations, cholera is an infectious disease (not genetic), and muscular dystrophy has lower prevalence in Caucasians compared to cystic fibrosis.

Answer:

cystic fibrosis.
