What is the test for determining whether a DNA profile of a suspect has been found in a DNA sample from the crime scene?

Once a match is found, the next question is the statistical significance of the match. (See People v. Wilson (2006) 38 Cal.4th 1237, 1242, 45 Cal.Rptr.3d 73, 136 P.3d 864.) This case involves that question. When a suspect's sample is compared to the crime scene evidence, and a match is found, "the DNA profile of the matched samples is compared to the DNA profiles of other available DNA samples in a relevant population database or databases in order to determine the statistical probability of finding the matched DNA profile in a person selected at random from the population or populations to which the perpetrator of the crime might have belonged." (People v. Soto (1999) 21 Cal.4th 512, 518, 88 Cal.Rptr.2d 34, 981 P.2d 958.) "Experts calculate the odds or percentages usually stated as one in some number that a random person from the relevant population would have a similar match." (People v. Wilson, supra, at p. 1239, 45 Cal.Rptr.3d 73, 136 P.3d 864.)
