narrow-sense heritability

(genetics)
The degree to which individual phenotypes are determined by the genes transmitted from the parents; expressed as the ratio of the additive genetic variance to the total phenotypic variance.

It indicates that the narrow-sense heritability cannot be achieved satisfactorily in complex diseases and traits with a complex inheritance such as human height (Eichler et al.
Many BLUP analyses have not fulfilled the narrow-sense heritability.
01) had a better performance than that of total SNPs in terms of narrow-sense heritability.
The broad-sense heritability and the narrow-sense heritability were estimated with the backcross method (WARNER, 1952), by the following expressions:
Given that genetic factors exert a large effect on the phenotype and an intermediate to high narrow-sense heritability was observed, the copper concentration appears to exhibit a qualitative inheritance.
The early generation narrow-sense heritability of the copper concentration of the common bean seed falls between intermediate (51.
Considering the significance of the variance of genotypes, Hayman method [4] was used to calculate the trait controlling genetic parameters including additive effect, dominance effect, average dominance degree, number of trait controlling genes, the ratio of the genes having positive and negative effects in parents, broad-sense and narrow-sense heritability, and graphic analysis.
