As I understand it, sickel-cell is a mixed dominance genetic trait. 1) Those without sickel-cell at all are at higher risk from malaria. 2) Those who are have both allels for sickel-cell tend, in primitive cultures, to die from the anemia. 3) Those with one allel for sickel cell have the benefit of malaria resistance (or reduced severity) with some "normal" blood cells. -- Drew Lawson Disclaimer: No disclaimer is needed as the entire universe exists only in my mind.
