Document Summary
Our desire to identify a single cause of an event. It is an adaptive part of human thinking. Sometimes events occur and our first inclination is to find the cause or person responsible for the event. This natural intuition also influences our thinking of development. Heritability = variance of genes divided by variance of genes + the variance of the environment + the variance of genes times the environment. It is a statistical estimate of the proportion of the measured variance (v) in a trait among individuals in a given population that is attributable to genetic differences among those individuals. It does not tell you how a trait develops. This is just quantifying traits from an entire population but does not speak anything about the individual. There is not a specific developmental process that is explained by this. This is a modification of the correlation statistic.
