Second Generation Multiplex Plus (SGM Plus), is a DNA profiling system developed by Applied Biosystems.
[5] The Human Genetics Commission has reported that the random match probability is in the region of 1 in a trillion.
However it stated "When the SGM Plus profiling system was first introduced, there was agreement within the scientific community that identifications with match probabilities lower than one in a billion would not be quoted in the courts of law, so as to avoid overstating the value of the DNA evidence to take into account that match probabilities are only estimates, and to make sure that the figure used was one that was meaningful to non-specialists."
[6] The UK Crown Prosecution Service states "SGM Plus DNA profiling is very discriminating between individuals.
The probability of obtaining a match between the profiles of two unrelated individuals by chance is very low, of the order of 1 in a billion.
