WebbWith simple DNA evidence, there is only one genotype possibility. Random match probability (RMP) tells us the chance of making a mistake. RMP gives the probability that someone unrelated to the defendant matches the DNA. The strength of evidence, or likelihood ratio (LR), is one over the RMP. http://www.cjig.cn/html/jig/2024/3/20240309.htm
