No, for some traits the value of phenotypic and genetic correlation is the same. However, for some other traits the value of phenotypic correlation is smaller than the genetic correlation as discussed in this video. For instance, the genetic correlation between birth weight and yearling weight in beef cattle is (0.70) higher than the phenotypic correlation between these two traits (0.35).
Sir is it necessary that pheotypic correlation value should be high than genotypic correlation value??
