Concept
Breeder's equation, R = h²S, is a fundamental formula in quantitative genetics that predicts the response to selection, where R is the response to selection, h² is the heritability, and S is the selection differential. It provides a framework for understanding how traits evolve under artificial or natural selection, assuming a linear relationship between phenotype and genotype.
Concept
Narrow-sense heritability is the proportion of phenotypic variance in a population that is attributable to additive genetic variance, which can be passed from parents to offspring. It is crucial for predicting the response to selection in breeding and evolutionary studies, as it reflects the potential for a trait to evolve under natural or artificial selection.
