Table 3 -- Genetic assessments of greenback cutthroat trout. Under results, h denotes that the sample was believed to contain hybridized fish and p denotes the sample was deemed genetically pure. Method refers to the technique used to ascertain genetic status: m, meristic-morphometric assessment; e, electrophoretic analysis of allozymes; and d, examination of mitochondrial or nuclear DNA. For each analysis, the year or years from which samples were drawn and the sample size (N) are noted. Within a particular water, identical samples evaluated on more than one occasion are marked with an asterisk (*). Missing data are denoted by a dashed line.
