Interpretation
Genetic Inheritance and Carrier Rates Interpretation
Nature, in her evolutionary pragmatism, rigged the lottery of human genetics such that those whose ancestors survived the relentless culling of malaria in Africa, the Mediterranean, and India now pass on a sickle-shaped key to that past survival, along with the heavy, attendant lock of a modern disease.
