Additive genetic variance for resistance to columnaris disease in two rainbow trout breeding populations explained by 1-Mb sliding SNP windows. The results shown are from iteration 2 of the weighted single-step genome-wide association study (wssGWAS). The year-class 2015 populations are from the USDA-ARS national center for cool and cold water aquaculture (NCCCWA) and from the Troutlodge, Inc. USA May spawning nucleus population (TLUM)
