Witryna1 wrz 2024 · The heritability genetic parameter is represented by an index (0 < h 2 < 1) that evaluates the proportion of the phenotypic variation of a trait that is of genetic origin in a specific population (i.e., additive variance, A in the equation). This index is used to predict the promptness of response of a selected trait. 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.
