- Hybridization with introduced rainbow trout threatens most native westslope cutthroat trout populations. Understanding the genetic effects of hybridization and introgression requires a large set of high-throughput, diagnostic genetic markers to inform conservation and management. Recently, we identified several thousand candidate single nucleotide polymorphism (SNP) markers based on RAD sequencing of 11 westslope cutthroat trout and 13 rainbow trout individuals. Here we used flanking sequence for 56 of these candidate SNP markers to design high-throughput genotyping assays. We validated the assays on a total of 92 individuals from 22 populations and seven hatchery strains. Forty-six assays (82%) amplified consistently and allowed easy identification of westslope cutthroat and rainbow trout alleles as well as heterozygote controls. The 46 SNPs will provide high power for early detection of population admixture and improved identification of hybrid and non-hybridized individuals. This technique shows promise as a very low-cost, reliable, and relatively rapid method for developing and testing SNP markers for non-model organisms with limited genomic resources.
- RAD_Diagnostic_CombinedChip_CallMapData provided in the following .csv file are from Fluidigm EP1 call map output. See the Fluidigm documentation for details on field names. The chip run used to generate the data is a composite of reads taken after 42 and 46 cycles.
