Heritability estimation
Heritability 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. The concept of heritability can be expressed in the form of the following question: "What is the … Zobacz więcej Heritability measures the fraction of phenotype variability that can be attributed to genetic variation. This is not the same as saying that this fraction of an individual phenotype is caused by genetics. For example, it is … Zobacz więcej Since only P can be observed or measured directly, heritability must be estimated from the similarities observed in subjects varying in their level of genetic or environmental … Zobacz więcej Heritability estimates' prominent critics, such as Steven Rose, Jay Joseph, and Richard Bentall, focus largely on heritability estimates in behavioral sciences and social sciences. Bentall has claimed that such heritability scores are typically calculated … Zobacz więcej Any particular phenotype can be modeled as the sum of genetic and environmental effects: Phenotype (P) = Genotype (G) + Environment (E). Likewise the phenotypic variance in the trait – Var (P) – … Zobacz więcej In selective breeding of plants and animals, the expected response to selection of a trait with known narrow-sense heritability Zobacz więcej • Behavioral genetics • Heredity • Heritability of IQ Zobacz więcej • Lynch M, Walsh B (1998).

WitrynaThe database to estimate the heritability (h 2) included all the sample horses (n = 2,098) and their sires and dams. Additionally, all the ancestors available in the Chilean Horse Stud Book were included in the database for 297 sampled horses including those with locomotor stereotypies. The genealogical database consisted of 7,187 individuals.
