As of mid-2021, it is estimated that over 50 percent of DNA laboratories in the US have implemented a probabilistic genotyping (PG) software for DNA interpretation. Another 20-30 percent of laboratories are in the process of procuring, validating, or implementing a PG system within the next 2-3 years. I will discuss the advantages of probabilistic genotyping compared to current methods and how a number of these software programs work (focusing on those that use Markov Chain Monte Carlo simulations). An explanation of how the Likelihood Ratio is assigned by the PG software will be presented. ). Finally, I will address some of the current legal challenges to probabilistic genotyping software systems in the US courts.
