Witryna6 wrz 2012 · The age at maximum heritability was noted for each trait. Narrow-sense heritability, defined as the proportion of the phenotypic variance attributable to additive genetic effects, was estimated as h 2 = σ 2 G /σ 2 P, where σ 2 G is the additive genetic variance and σ 2 P is the total phenotypic variance. WitrynaHeritability the degree to which the phenotypic variation of any trait in a population of animals or plants (or group of them) is determined by the genotypic differences among individuals.

WitrynaBroad-sense heritability (H2) represents the proportion of phenotypic variance that is due to genetic variance. It is calculated by dividing the genetic variance by the … WitrynaEven if we want heritability to be interpreted in the rst sense, as a partition of variance, this will not, in general, be correct. All we have access to from the data is an estimate of something like heritability in sense 2. High heritability means that individuals with similar genotype are likely to have similar trait values.
