Forensic statistics is the application of probability models and statistical techniques to scientific evidence, such as DNA evidence, [1] and the law. In contrast to "everyday" statistics, to not engender bias or unduly draw conclusions, forensic statisticians report likelihoods as likelihood ratios (LR).
Modern day technology has evolved beyond RFLP. Short Tandem Repeat (STR) analysis is the modern day equivalent of RFLP. Not only does STR analysis use less of a sample to analyze DNA, but it also is a part of a larger process called Polymerase Chain Reaction (PCR). PCR is a process that can be used to quickly reproduce up to a billion copies of ...
DNA profiling (also called DNA fingerprinting and genetic fingerprinting) is the process of determining an individual's deoxyribonucleic acid characteristics.DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding.
The first formal bloodstain training course was given by MacDonell in 1973 in Jackson, Mississippi. MacDonell taught workshops on how to conduct bloodstain analysis, and the newly trained bloodstain analysts, who often had received as little as 40 hours of instruction, in turn would give expert testimony in court cases.

STR analysis is a tool in forensic analysis that evaluates specific STR regions found on nuclear DNA. The variable (polymorphic) nature of the STR regions that are analyzed for forensic testing intensifies the discrimination between one DNA profile and another. [3] Scientific tools such as FBI approved STRmix incorporate this research technique.
A now-former forensic scientist with the Colorado Bureau of Investigation (CBI) manipulated DNA test results in hundreds of criminal cases, an internal affairs investigation found, which prompted ...
