Definition
The genetic coefficient of variance, specifically the coefficient of additive genetic variance, is a mean-standardized index of the evolvability of a trait (Hill 2010; Houle 1992). In other words, it reflects the potential for a particular trait to respond to selection pressures on a particular population. The larger the coefficient, the greater the evolvability of the trait.
Introduction
One of the most important concepts in quantitative genetics and the study of evolution is that of evolvability, or a trait’s capacity for adapting to various selection pressures to which a population is subject. Researchers have attempted to quantify this construct in numerous ways, particularly the coefficient of additive genetic variance (CVA) and the narrow-sense heritability estimate (Hansen et al. 2011). This section focuses on the former by discussing how one mathematically obtains the CVA and why it is the preferred...
