Here are the overall summary of the strengths and limitations of forensic DNA profiling.

[center]Forensic DNA Profiling: Overall Strengths[/center]

1. It can be extremely discriminating, due to low random probabilities.
2. It is extremely sensitive, meaning that DNA profiles can be successfully determined from very low quantities of DNA.
3. It can be successfully developed from bodily fluids and from other sources such as hair and shed skin cells.
4. Multiple testing systems are available thereby increasing the likelihood of successfully generating DNA profiles.
5. Current technologies may permit individual DNA profiles to be readily determined even when mixed in samples with DNA from other individuals.

[[center]b]Forensic DNA Profiling: Overall Limitations[/b][/center]

1. The random probability is reported when an individual (e.g Mr. U) cannot be excluded as the source of a DNA profile. Relatives of Mr. U will have a higher probability of coincidentally sharing the crime scene profile than randomly selected people would.
2. It’s not uncommon to find low levels of DNA on various surfaces and objects, whether a crime has occurred or not. Sterilization does not guarantee DNA-free.
3. Searching evidence for sample on which to perform DNA testing is challenging. The process is low-tech, meticulous, labor-intensive and subject to error. Possibility of fake (synthetic) DNA.
4. A failure to exclude someone using either mtDNA or Y-STR testing is different than when using standard STR testing.
5. Low levels of DNA in mixture pose greater challenge and interpretation may carry a higher risk of error.
