It is the very simplicity of DNA evidence that allows it to be presented numerically at all. And yet, as Rudin and Inman point out, there is still much debate about how to present this evidence. It could be argued that the presentation of scientific evidence should bend to conform to the courts’ requirements. Indeed a court can almost compel this. There have been several rulingsb on this subject by courts, which have been used to argue for or against particular approaches to the presentation of evidence.
Pr(HpԽE,I) This approach would work just as well. High numbers would be support for Hd, typically the defense hypothesis. Is the reason we defined it with Hp on top an indication of subconscious bias? Is this the reason Balding, Donnelly, and Nichols42 wrote their LR’s up the other way? Were they trying to help us see something? Under the coincidence approach, this would be the match that is caused by the suspect being the donor of the crime stain or by a coincidence. To make the comparison with hypothesis testing, we would formulate H0: The DNA came from a male not related to the suspect.
The term is reserved for loss of complete repeat units. For tetrameric loci, the loss of one unit is termed the N − 4 stutter and the loss of two units is the N − 8 stutter. Stuttering is presumed to be due to miscopying or slippage during the PCR process. It is useful to define stutter ratio as SRϭφS / φA and stutter proportion as SxϭφS / (φA+φS). Larger alleles appear to stutter more. Specifically, strong supporting evidence has been given by Klintschar and Wiegand467 for the hypothesis that the larger the number of homogeneous repeats, the larger the stutter peak.
