Laboratories typically provide STR profile frequency estimates in three to four population groups. The reason for this is to provide a range of estimates from which to conclude the significance of matching DNA profiles.
For a discussion of the use of multiple population group statistical evidence, see People v. Wilson (11/16/04) Cal. Ct. App., A101459, 2004 Cal. App. Lexis 1918; People v. Pizarro Cal. App. 110 Cal. App. 4th 530 (2003).
