 To enhance the disambiguation, Taylor (2012) recommends the use of terms familiar in agricultural trials: variety instead of genotype (in the sense of classes of individuals related by genealogy from a common ancestor or set of ancestors), location instead of environment, and trait instead of phenotype (given that this last term implies a connection with a set of genotypes, in the sense of pairs of genes). Whether or not the alternatives terms get more widely adopted, once the gap between statistical patterns from quantitative genetics and measurable underlying factors is recognized and consistently observed, it becomes difficult to follow the reasoning of accounts that conflate or slip between the disparate meanings of “genetic”. This difficulty extends to accounts of the interaction between genes or genotypes and environment that overlook the distinction, proceeding then as if interaction as defined in quantitative genetic analyses of variation has some conceptual or empirical connection with statistical interaction between measured presence of genes and environmental variables. (It is beyond the scope of this entry to review such accounts by scientists or philosophers; see Taylor 2015 as well as discussion in Section 6.5 on what the conflation or ambiguity signifies.)
