Notes
Omission of the indices suggests misleadingly that the terms of the models refer to some measurable variables (or properties of the genotypes and environments) that exist independently of the specific set of genotypes and environments from which the genotypic values etc. are estimated.
Arguments that “genotype-environment interaction” might be negligible or hard to detect in humans generally use the term in a sense in which “genotype” denotes a value of a measured genetic factor and/or “environment” denotes a value of a measured environmental factor (e.g., Plomin et al. 1977, Moffitt et al. 2005). Genotype-environment interaction in the sense used by plant breeders involves no measurable factors.
Methods of indirect translation requires replication and control of conditions possible only in agricultural and laboratory trials (Taylor 2009).
