Question

phenotypes in the case of g6pd deficiency? choose 1 answer: a genotype phenotype (no fava beans in diet) phenot (fava beans i diet) g6pd mutation no anemia anemia no mutation no anemia anemia b genotype phenotype (no fava beans in diet) phenot (fava beans i diet) g6pd mutation no anemia anemia no mutation no anemia no aner c genotype phenotype (no fava beans in diet) phenot (fava beans i diet) g6pd mutation anemia. anemia no mutation no anemia no aner

Explanation:

G6PD deficiency: Individuals with G6PD mutation develop anemia only when exposed to fava beans (trigger). Those without mutation don't get anemia even with fava beans.

• Option A: “No mutation” shows anemia with fava beans, wrong (no mutation should not react to fava beans).
• Option B: “G6PD mutation” → anemia with fava, no anemia without; “No mutation” → no anemia either way. Correct.
• Option C: “G6PD mutation” shows anemia without fava beans, wrong (mutation causes anemia only with trigger).

Answer:

B.
Genotype | Phenotype (no fava beans in diet) | Phenotype (fava beans in diet)
--- | --- | ---
G6PD mutation | no anemia | anemia
No mutation | no anemia | no anemia
