Lesson plan
Second Generation Multiplex Plus
Second Generation Multiplex Plus (SGM Plus), is a DNA profiling system developed by Applied Biosystems. It is an updated version of Second Generation Multiplex. SGM Plus has been used by the UK National DNA Database since 1998. An SGM Plus profile consists of a list of 10 number pairs, one number pair for each of 10 genetic markers, along with two letters (XX or XY) which show the result of the Amelogenin sex indicating test. Each number pair denotes the two allele values for the marker - one value is inherited from each of the subject's parents. If both alleles are the same, then only a single number, rather than a pair, is recorded.
