Answer:
B
Step-by-step explanation:
While humans have the same genome, there bear very minute differences (0.01%) between individuals that make them different from one another. The closer you are in a hereditary relationship, the lower this difference. This difference can be used to determine the genetic relationship and is called a DNA fingerprint.
It involves cutting up DNA from a sample using restrictions enzymes and then running the sample on an electrophoresis gel. The resulting bands are compared between two individuals. The more the bands align, especially at regions where people differ alot such as Short Tandem Repeat regions, the higher the genetic relationship between the two.
