 There is an alternative to restoration of the distinction between genotypic variance and variation in actual genotypes, which is to focus on the latter. As determining the sequence of DNA at any stretch of the genome (i.e., of the genotype-as-material-constituents) has become routine, Genome-Wide Association (GWA) studies allow estimation of the fraction of the variation in the trait that is associated with measurable genetic variants. (The variants studied are single-nucleotide polymorphisms [SNPs], which are not held to be the DNA influencing the trait, but simply somewhere close to those factors on the genome.) It turns out, however, that, even when many genetic variants are examined together, only a small fraction of the variation in the trait is associated with—or in statistical terms, “accounted for” by—the genetic variants (McCarthy et al. 2008). This finding has led to discussions about missing heritability (e.g., Manolio et al. 2009). This new heritability has, however, no conceptual or empirical connection with the heritability of quantitative genetics. To the extent that the additional ambiguity in use of the term heritability is associated with the unfulfilled expectation that high heritability means genetic variants might account for a large fraction of trait variation, the restoration identified in the previous paragraphs is warranted.
