There is 128 people with no disease and 397 with disease. Out of people with disease, 256 tested positive. Out of people with no disease, 1 tested positive. Suppose general disease probability is 0.1. What's the probability that a randomly picked person infected with the disease tests negative? (use Bayes theorem)

Sickle-cell anemia is an autosomal recessive disease, people with the disease have a ss genotype and people without the disease have a SS genotype. People who have the disease get very ill, but people who have only one copy of the recessive gene are actually protected from getting malaria (Ss heterozygote genotype). Which area of the world is the frequency of sickle cell anemia the highest? Why do you think this is true (related to heterozygote advantage)? We talked about...
