PSY352H5 Midterm: review of test questions with answers
Document Summary
Psy252 review: define heritability using mathematical model and explain the scientific definition as well, heritability is defined as the ratio of genotypic variance (vg) to the phenotypic variance (vp) of a particular trait. Explain how this would be possible and what this would mean in terms of environmental and genetic effects. If we assume that the heritability of iq is 100%( hypothetically) then, www. notesolution. com. In a population, with a homogeneous environment for every individual, 100% of the variability in iq found in the population will be based on genetic factors. This means that variations in the population will be based entirely in genetic effects: however, this does not mean that the environmental effect is negligible. If the environment effect for half of the population changes then heritability value is not valid. Also the population in a homogeneously poor environment may have an overall average iq that is lower than that of population that is in rich environment.
