What is the test for determining whether a DNA profile of a suspect has been matched to the crime scene evidence?

If a match is found, the next question is the statistical significance of the match. ( Henderson, supra, 107 Cal.App.4th at p. 778, 132 Cal.Rptr.2d 255; People v. Wilson (2006) 38 Cal.4th 1237, 1242, 45 Cal.Rptr.3d 73, 136 P.3d 864.) The analyst calculates the statistical probability that the DNA profile of a person, selected at **402 random from the relevant population, would contain the same pattern of alleles represented in the evidence sample. ( Venegas, supra, 18 Cal.4th at p. 65, 74 Cal.Rptr.2d 262, 954 P.2d 525.)

When a suspect's sample is matched to the crime scene evidence, "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." ( Soto, supra, 21 Cal.4th at p. 518, 88 Cal.Rptr.2d 34, 981 P.2d 958.) "Experts calculate the odds or percentagesusually stated as one in some numberthat a random person from the relevant population would have a similar match." ( People v. Wilson, supra, 38 Cal.4th at p. 1239, 45 Cal.Rptr.3d 73, 136 P.3d 864.)
