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?
A student in lab has just used their mtDNA chromatogram to construct a list of mutations found in their sequence. Based on the key mutations found in their sequence, they believe they belong to either haplogroup Q or haplogroup M1.
The presence of which mutation would help them determine between haplogroup Q or haplogroup M1?

- DNA fingerprinting is now widely used to tie a particular suspect to the DNA samples found at a crime scene. What does this mean? O a. DNA from the crime scene that matches an individual is unique to that person versus anyone on the whole planet O b. DNA fingerprinting is not that accurate O c. The DNA fingerprint must be taken from a database like DNA ancestry and cannot be collected from an individual who is a suspect O d. DNA from the crime scene may match more than one person on the whole planet e.
