Section 26.26A.300 - Definitions-Genetic testing-RCW 26.26A.300 through 26.26A.355The definitions in this section apply throughout RCW 26.26A.300 through 26.26A.355 unless the context clearly requires otherwise.
(1) "Combined relationship index" means the product of all tested relationship indices.(2) "Ethnic or racial group" means, for the purpose of genetic testing, a recognized group that an individual identifies as the individual's ancestry or part of the ancestry or that is identified by other information.(3) "Hypothesized genetic relationship" means an asserted genetic relationship between an individual and a child.(4) "Probability of parentage" means, for the ethnic or racial group to which an individual alleged to be a parent belongs, the probability that a hypothesized genetic relationship is supported, compared to the probability that a genetic relationship is supported between the child and a random individual of the ethnic or racial group used in the hypothesized genetic relationship, expressed as a percentage incorporating the combined relationship index and a prior probability.(5) "Relationship index" means a likelihood ratio that compares the probability of a genetic marker given a hypothesized genetic relationship and the probability of the genetic marker given a genetic relationship between the child and a random individual of the ethnic or racial group used in the hypothesized genetic relationship.Added by 2018 c 6,§ 401, eff. 1/1/2019.
