B. The frequency of the disease is unusually high in a small group of genetically related individuals who live in southern Spain.
C. The disease symptoms usually begin around the age of 40.
D. It is more likely that both monozygotic twins will be affected by the disease than will dizygotic twins.

We often speak of diseases such as phenylketonuria (PKU) andachondroplasia as having a genetic basis. Explain whether the followingstatements are accurate with regard to the genetic basis ofany human disease (not just PKU and achondroplasia).A. An individual must inherit two copies of a mutant allele to havedisease symptoms.B. A genetic predisposition means that an individual has inheritedone or more alleles that make it more likely that she or he willdevelop disease symptoms than other individuals in a populationwill.C. A genetic predisposition to develop a disease may be passedfrom parents to offspring.D. The genetic basis for a disease is always more important thanthe environment.
