Deoxyribonucleic acid (DNA) is complex molecule present in nearly every cell of the human body that contains all of an individual’s genetic material. Trace DNA has allowed DNA to be detected on everyday objects such as door handles, tables and chairs. Currently, the idea of the secondary transfer of DNA has arisen, involving the transfer of genetic profiles from an individual through a vector and then to final individual or object. This has become a reoccurring term in the court system, as individuals standing trial use this argument for the presence of their DNA. It is therefore hypothesized that through the exploration of literature and completion of a meta-analysis that an appropriate and concise guide will be produced to determine the chances of a secondary transfer event occurring and what conditions are required, to aid Biologists in expert testimony. Database searches were conducted to gain resources in the topic, followed by a number of screens to determine the suitability of articles for the meta-analysis. With the resultant 38 articles, data extraction was additionally carried. However, due to the lack of quantitative variables and results, a meta-analysis was not able to be conducted. It is suggested that in the future, studies publish their results in a more scientifically rigorous manner or allow the access of raw results for external interpretation purposes.
