Question

In a criminal trial in which DNA fingerprinting has been used, a genetic "match" between the suspect and evidence left at the crime scene provides:
A) definitive proof that the suspect is guilty.
B) a high probability that the suspect is guilty.
C) a low probability that the suspect is guilty.
D) definitive proof that the suspect is innocent.

Answer 1

Hint: If the suspect and evidence left at the crime scene match each other then it shows that the suspect must be guilty and this is checked by a well-known technique DNA fingerprinting that is used to check the genetic match.
Complete step-by-step answer:
DNA fingerprinting is also called DNA profiling, DNA typing, identity testing, and genotyping. In genetics, it is a method of isolating and identifying different elements within the base-pair sequence of DNA.DNA fingerprinting is a technique used to determine the identity of a person based on the nucleotide sequences of certain regions of human DNA that are unique to individuals. Only 1-2% of DNA is unique and another 98-99%DNA is the same or junk DNA. DNA fingerprinting is used in many situations, like criminal investigations, forensic purposes, and paternity testing. In the situations like a genetic match between a suspect and evidence found at the crime scene, one aims to “match” two DNA fingerprints with one another. Although DNA fingerprinting is a powerful technique, a genetic match can demonstrate only a high probability of being guilty as there is a 1/100,000 to 1 / 1,000,000,000 chance that two individuals will share the same genetic makeup. So DNA fingerprinting does not give definite proof that the suspect is guilty. And as there is a match between the suspect and evidence left at the crime scene that shows that the suspect is not innocent. DNA fingerprinting is a test that shows the genetic makeup of a person or other organisms. It's used as evidence in courts, to identify bodies, and to track down blood relatives.
Hence the correct answer is option (B), with a high probability that the suspect is guilty.
