Witryna5 gru 2011 · This is our first in a series of papers exploring the explanations for missing heritability. Geneticists define the proportion of (narrow-sense) heritability of a trait explained by a set of known genetic variants to be the ratio π explained = h 2 known /h 2 all, where (i) the numerator h 2 known is the proportion of the phenotypic variance … WitrynaHeritability •Central concept in quantitative genetics •Fraction of phenotypic variance due to additive genetic values (Breeding values) –h2= V A /V P –This is called the narrow-sense heritability –Phenotypes (and hence V P) can be directly measured –Breeding values (and hence V A) must be estimated •Estimates of V A require …
