The compilation is not intended to be exhaustive, but to give a general picture of the empirical correlations found in different studies with several marker-based estimators of inbreeding. F_VR1 and F_VR2: Estimators described by VanRaden [19]. F_YA1 and F_YA2: Estimator proposed by Yang et al. [20] and modified by Zhang et al. [34]. F_LH1 and F_LH2: Estimators derived by Li and Horvitz [16]. F_HOM: Average marker homozygosity. F_ROH: Estimator from Runs of Homozygosity. Averages in each cell in bold face and the range of values are shown below it
