This process is experimental and the keywords may be updated as the learning algorithm improves. If H2 is non-zero, genetic differences have influenced variation between individuals, if 0, does not neccesarily mean genes are relevant H2 is limited in. These keywords were added by machine and not by the authors. These types of information will help them in predicting the evolutionary dynamics of a whole population with reference to a particular trait (Waldmann 2001 Fisher et al.
A large number of investigators across the world are engaged in determining the significance of both the genetic and environmental factors in regulating the phenotypic expression of a particular trait. These sources of phenotypic variations decide whether that trait has an evolutionary potential and holds an ability to respond to natural/artificial selection or whether it can respond to environmental variations. Each of these sources signifies a distinctive underlying origin. Within a population, there are numerous potential sources of phenotypic variations.
