The incidence of a rare autosomal recessive genetic disorder, Tay-Sachs, is approximately 1 in 3,500 in a certain population. Assuming that this population is in Hardy-Weinberg equilibrium, what is the probability that a phenotypically normal female with no family history, and a phenotypically normal male who had an affected great-aunt, will have a child who is a carrier for Tay-Sachs?
