Glossary - Match Probability


Match Probability

The probability of a random match of a genetic profile within a population. For example, a match probability of 1:10 (i.e., 0.1) indicates that there is a 0.1 (i.e., 10%) chance of a random match in the population, whereas a match probability of 1:100 (i.e., 0.01) indicates that there is only a 0.01 (i.e., 1%) chance of a random match in the population. A 1:100 match probability is therefore a better indication that two samples are derived from the same individual than a match probability of 1:10.
