Sevenmile Creek. All 26 successfully amplified individuals in this population displayed 

 only PrNE fragments diagnostic of westslope cutthroat trout. With a sample size of 24 

 individuals, we have a 96% chance of detecting as little as 1% hybridization with 

 rainbow trout and an 88% chance of detecting as little as 1% hybridization with 

 Yellowstone cutthroat trout. 

 Sincerely,
