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 ... WebThe phenotypic variance is sub-divided into genotypic variance (VG) and environmental variance (VE): VP= VG+ VE (We are ignoring any correlation or interaction between genes and environment.) The genotypic variance describes how much phenotypic variance is due to genetic differences within a population.
Web4. sep 2001 · The drawback of low phenotypic variance is elucidated in the next equation for the rate of change of the average phenotype of the group: ˙xavg ≈ V ⋅ f1 + { I CT (˜x − xavg)}, [9] where x̃ is the average phenotype of the external input of biomass.
