An individual has one of three genotypes called dd, dD, and DD, respectively, for a gene associated with disease X. The probability that an individual has genotype dd is 0.64; the probability that an individual has genotype dD is 0.32; and the probability that an individual has genotype DD is 0.04. The probability that an individual with the dd genotype is affected with disease X is 0.05. The probability that an individual with the dD genotype is affected with disease X is 0.80. The probability that an individual with the DD genotype is affected with disease X is 0.99. What is the probability that an individual is affected with disease X? Given that an individual has disease X, what is the probability that the individual is genotype dD?
