Webheritability for different genetic architectures, for designing association studies, for calculating power of association studies, and for studying the influence of population … WebHeritability, additive genetic variance and phenotypic variance are all parameters that refer to a population. If we sample the same population and randomly select another group of families, we would get slightly different results. 3. We have no inherent interest in the blocks or sites used in the experiment.
