Nuiii,....,!il~,#88' <br /> <br />Cover: (Top) Typical stream habitat of westslope cutthroat trout (Salmo clarki lewisi), Rattlesnake Creek, a tributary of the Clark Fork of the <br />Columbia River. The trout in this stream are a hybrid swarm of native westslope cutthroat trout and introduced rainbow trout (Salmo <br />gairdneri). Photo: Terilyn D. Allendorf. (Bottom) Plot of first principal component scores (PC I) of genotypes at 14 polymorphic protein loci <br />versus proportion of westslope cutthroat trout genes at six diagnostic protein loci in a sanJple of 30 trout from Rattlesnake Creek. Eighteen <br />fish had onlywestslope cutthroat trout genes at the six diagnostic loci; these 18 trout are represented by a single fish on the plot. One fish had <br />only rainbow trout genes at these loci. lbe other 11 fish had various combinations of rainbow and cutthroat trout genes, indicating that they <br />were first or later generation interspecific hybrids. This figure indicates that PC 1, which accounts for 44% of the genotypic variation in the <br />trout sampled from this stream, is almost completely explained by genetic differences between the two parental species contributing to this <br />hybrid swarm.
