Abstract: Common plug-in approach neglected sample size in quantifying DNA evidence. It leaded to inaccurate results and overweight DNA evidence. The formula of calculating likelihood ratio (LR) was obtained when Bayes model was used. Two numerical examples were separately calculated according to the Bayes method and the common plug-in approach. The results showed that the Bayesian method was more conservative and accurate than that of the plug-in approach.
