Narrow sense heritability example
WitrynaNarrow-sense heritability measures the part of variance attributable in a population to the additive effect of genes, independently of interaction effects between ... Thus, for example, an estimate of heritability of 0.60 does not mean that 60% of a particular person’s trait is explained by their genes. What it does mean, is that in a given ... Witryna4 maj 2024 · There are two different types of heritability: broad-sense heritability and narrow-sense heritability. What we’ve been discussing so far is broad-sense heritability: the proportion of phenotypic variance that can be explained by ALL genetic differences among individuals.
