WitrynaThis turned out to be 1.342. And then attempted to calculate heritabilty as Va/Vp = (4*0.098)/ (1.342 + 0.098) = 0.39. This is quite different from my slope estimate, and I'm not sure if my reasoning is correct. I've tried things with the sommer and heritability packages of R but haven't had success using either for a half-sib design and haven ...

WitrynaMisconception 4. “A heritability is a fixed value” The heritability reflects the relative weight of the genetic variance component in the phenotypic variance of a specific population and is based on observations that were taken on a specific moment in time. The magnitude of heritability depends on genetic variance in
