For all-or-none characteristics, this value can be
For all-or-none characteristics, this value can be translated from a continuous liability scale by multiplying by z squared times a polynomial of the incidence. This value is equal to the response to selection divided by the strength of selection in an artificial selection experiment. One version of this quantity solely accounts for additive effects. This quantity is commonly derived by taking the formula P equals G plus E, taking the variance of both sides, and setting the covariance term equal to zero. Falconer's formula is used to calculate this quantity in one type of study, in which monozygotic and dizygotic twins are compared for (*) concordance of a particular state. The narrow-sense and broad-sense versions of this quantity are denoted with lowercase and uppercase h-squared, respectively. This value can be inflated when maternal effects or other shared environmental factors are not accounted for. AR Jensen famously stated that this value is 1 for IQ, a result heavily criticized by Stephen Jay Gould. For 10 points, name this parameter which describes how much the genotype influences the phenotype.
