Phenotypic variation equation
WebFirstly, effects are expressed in terms of variance components rather than genotypic relative risks. Secondly, it is possible to consider the scenario where the test locus is a marker in LD with the true QTL. The total QTL variance should range between 0 and 1. For example, 0.05 represents a QTL that accounts for 5% of the phenotypic variance. WebThe formula is H b 2 = 2 ( r m z − r d z ) {\displaystyle {H_{b}}^{2}=2(r_{mz}-r_{dz})} where H b 2 {\textstyle {H_{b}}^{2}} is the broad sense heritability, r m z {\displaystyle r_{mz}} is the …

Web16. nov 2024 · Repeatability (r) is defined as r = (VG + VEg)/VP, where VG is the genetic variance, VEg is the general environmental variance, and VP is the total phenotypic variance. From replicate measures taken within a year, we assume VEg is small, so the repeatability is approximately the proportion of total variance of a trait that is due to genetic ...
