WebTherefore, the phenotypic effects of its inverse, developmental instability, are measured. To accomplish this, we must partition the phenotypic variation caused by extrinsic factors such as the genotype and environment from variation arising from intrinsic perturbations. The most common measure used is fluctuating asymmetry (FA). Web1 day ago · To partition and quantify potential sources of single-tissue PZM burden, we fit linear models relating technical and biological metadata to single-tissue PZM burdens and selected the best fitting model identified from detailed model comparisons .
