WebHeritability is a statistic used in the fields of breeding and genetics that estimates the degree of variation in a phenotypic trait in a population that is due to genetic variation between individuals in that population. [1] The concept of heritability can be expressed in the form of the following question: "What is the proportion of the ... WebKeywords: fundamental theorem, evolution, Price equation, breeder’s equation, average excess. Fisher’s fundamental theorem of natural selection states that natural selection increases the mean fitness at a rate equal to the additive genetic variance for fitness (Fisher 1930). The name he bestowed on it makes it clear that he viewed it as a
