The symbol for this quantity is a letter raised to the second power,  even though it is not a squared quantity.
This parameter was the subject of Zuk et al.'s Limiting Pathway model, which sought to explain the fact that this  parameter has been "missing" in human genetics. In selection experiments, this parameter is often calculated as the ratio  between the response value and the initial differential. The symbol for this quantity is a letter raised to the second power,  even though it is not a squared quantity. Twin studies are useful in measuring this quantity, one form of which ignores the  effect of (*) dominant/recessive patterns and epistasis and only focuses on the effect of additive alleles, which is symbolized V  sub A. For 10 points, name this parameter that is reported in its "narrow" and "broad" senses, describes the extent to which  variation in phenotype is due to variation in genotype, and is denoted h-squared.
