Answer: New York, NY (September 18, 2017) - The use of genetic data to establish a physiological basis for violent or impulsive criminal behaviors is occurring more frequently in criminal trials. However, a new review finds that genetic evidence used in the courtroom is not likely to be effective in convincing judges and juries that the defendants are less culpable for their actions. Evidence for a link between gene variants and criminal behavior has been tenuous.

However, the relationship between the gene's activity, environmental factors, and criminal behavior is unclear.
