Question
The allele for the sickle cell mutation is most common in
Blank______.
Multiple choice question.
- America
- Southern Africa
- Central Africa
- Northern Africa
Solution
The allele for the sickle cell mutation is most common in Central Africa.
Explanation:
The sickle cell mutation is a genetic adaptation that is particularly prevalent in regions where malaria is endemic. This mutation provides some level of protection against malaria, which has historically been a significant health issue in certain parts of Africa. While the sickle cell trait can be found in various populations around the world, particularly in Africa, the Middle East, and India, it is most commonly observed in Central Africa.
In Central Africa, the combination of high malaria prevalence and the genetic advantage offered by the sickle cell trait leads to a higher frequency of this allele in the population. In contrast, while Southern Africa does have instances of the sickle cell mutation, it is not as widespread compared to Central Africa. Therefore, when considering the geographical distribution of the sickle cell allele, Central Africa stands out as the region where this mutation is most frequently observed.
