  • The cross name is composed of the code for the dam used, followed by that for the sire. Two parental strains (Fraser and Nauyuk) and interstrain hybrids (F1) were used to produce backcross, F1, and pure strain families. N, the number of progeny included in each family on the basis of pedigree analysis. Note that 12-114 and 21-114 were selectively genotyped (15-25% of the least- and most-temperature-tolerant fish).
