- Identify a possible advantage and a possible disadvantage of a genetic test that would identify genes in individuals that increase their probability of having Alzheimer’s disease later in life.Select all the characteristics that make sickle-cell disease a good candidate to study genetic diseases. (Check all that apply.) Check All That Apply It is easily identifiable by a physical characteristic.It is easily identifiable by a physical characteristic. It results from a single change in a single gene.It results from a single change in a single gene. It can be influenced by the environment.It can be influenced by the environment. The sickle-cell inheritance pattern is not influenced by other genes.The sickle-cell inheritance pattern is not influenced by other genes.An important application of DNA fingerprinting is relationship testing. Persons who are related genetically have some bands or peaks in common. The number they share depends on the closeness of their genetic relationship. For example, an offspring is expected to receive half of his or her minisatellites from one parent and the rest from the other. The diagram shown here schematically illustrates traditional DNA fingerprints of an offspring, mother, and two potential fathers. In paternity testing, the offspring’s DNA fingerprint is first compared with that of the mother. The bands that the offspring have in common with the mother are depicted in purple. The bands that are not similar between the offspring and the mother must have been inherited from the father. These bands are depicted in red. Which male could be the father?
