The Mapping of Quantitative Trait Loci Associated with Morphometrics and Parr Marks in an F2 cross of European and North American Strains of Cultured Atlantic Salmon
Mapping quantitative trait loci (QTL) for traits under consideration for genetic improvement is becoming more common for many aquatic species, including Atlantic salmon. The objective of the study was to map QTL associated with length, weight, shape, parr mark number and contrast in three F2 hybrid...
