What are some limitations to DNA fingerprinting?

Answer 1

Well, one of the main problems with the process of DNA fingerprinting is that the sample can be easily ruined. The tiniest pieces of genetic junk can contaminate DNA samples, causing them to be useless. Although DNA fingerprinting requires a good sample to work with, this problem can be solved by using the newer technique called PCR. PCR can use extremely small samples of DNA and produce a much faster result. But this also means the DNA samples that PCR uses are even more likely to be contaminated because of their size, as it is harder to find a small sample with hardly any contamination. Another limitation of fingerprinting is that the procedure is so complex and hard to read the DNA patterns, that sometimes the juror finds the evidence almost invisible.

Although DNA Fingerprinting is a highly advanced process, there are still some things that it is unable to do. In dogs for example, a fingerprint does not make it possible to determine if the animal is a carrier of a disease causing allele. Also, a DNA fingerprint is unable to show a crossbreed in animals. This is because second or third generation crosses cannot be seen by working backwards in a pedigree. It may soon become possible to discover the crossbreed of dogs, although right now this is not possible

Answer 2

Some limitations to DNA fingerprinting include the possibility of sample contamination leading to inaccurate results, the need for high-quality DNA samples for reliable analysis, and the inability to differentiate between identical twins since they share the same DNA. Additionally, DNA fingerprinting cannot provide information on the timing of events or distinguish between close biological relatives without supplemental information.
