* Three of the Fraser strain individuals in the test set were also parents of the two half sib families utilized in GBS in SNP discovery.

^† Twenty-four of the Nauyuk strain individuals in the test set were also used in SNP discovery.

^⧧All 20 of the Mývatn lava cave fish in the test set were also used for SNP discovery
