Associations between morphological and physiological traits and yield components were established and potential trade-offs between various traits were identified.
The desired gains in the various traits were calculated based on the producers' preferences for traits and were used to weigh traits in the breeding objective using selection-index methodology.
When the phenotypic variance for the various traits was partitioned, triploids exhibited significantly greater additive genetic variance and maternal effects across all traits relative to diploid fish — indicating that gene dosage effects were primarily additive.
Clusters of more than five QTLs for various traits were identified on seven linkage groups.
The associations among glycerol, FFAs, and aforementioned FAs with various traits were evaluated by Pearson and partial correlations.
Often, phenotypic measures for various traits are available and the additive genetic relationship between individuals (W right 1922) can be derived, on the basis of the known pedigree.
Clusters of QTLs (more than five QTLs) for various traits were identified on LG2, 3, 7, 8, 10, 13 and 20 (Fig. 1).
As well as recording data on leg morphology, allometric scaling patterns of various traits were also compared; normally, aspects of hindlimb morphology would be expected to scale isometrically (that is, with geometric similarity) to body mass.
Genome-wide association studies, which typically report regression coefficients summarizing the associations of many genetic variants with various traits, are potentially a powerful source of data for Mendelian randomization investigations.
In the reciprocal cross (T×M), the various traits were not significantly different from those in the control crosses, except that mating duration doubled, with the male having observed difficulty disengaging from the female.
