This pay-for-view article at FSI Genetics should be made free-share for a certain period of time. Its focus on touch-DNA transfer interpretations suggests that the current opinions on DNA circumstances are suspect and standards are lacking. This is a very important subject since police crime labs have a way of “spinning’ these DNA interpretations for a particular purpose.
Highlights
- •Understanding the variables impacting DNA transfer is highly relevant
- •DNA transfer awareness is required to limit contamination risk
- •Dedicated training is required for experts providing opinion on DNA transfer
- •More research is required to generate probability estimates for more situations
