Epistatic interactions between genetic disorders of hemoglobin can explain why the sickle-cell gene is uncommon in the Mediterranean
Several human genetic disorders of hemoglobin have risen in frequency because of the protection they offer against death from malaria, sickle-cell anaemia being a canonical example. Here we address the issue of why this highly protective mutant, present at high frequencies in subSaharan Africa, is u...
