What would you expect to be the differences in the frequencies of mutant forms of G6PD in human populations living at different latitudes?

Question

Quizplus · Accepted Answer

G6PD deficiency is linked to protection against malaria because the parasite that causes malaria cannot replicate as effectively in red blood cells that have reduced G6PD levels. Malaria is more prevalent in tropical regions closer to the equator where the climate is warmer and wetter. Therefore, populations living in these regions are more likely to have a higher frequency of G6PD deficiency to provide protection against malaria. As latitude increases and environments become less tropical, the frequency of G6PD deficiency should decrease because the selective pressure for the trait is reduced.
