In addition, it is important to note that the probability of 1 in 1.5 billion is substantially increased if the actual source is a person related to the suspect, especially a sibling. An NDIS-approved and internally validated expert system may be used to complete the data-interpretation process. Methodology is used to describe the analytical processes and procedures used to support a DNA-typing technology: for example, extraction methods (manual vs. automated); quantitation methods (slot blot, fluorometry, real-time); typing test kit; and platform (capillary electrophoresis, real-time gel, and end-point gel systems).
