WebAug 1, 2024 · The mean inbreeding coefficients of each breed observed in the present study (0.9 % Charollais – 4.4 % Belclare) were consistent with mean inbreeding coefficient estimates from the analyses of other purebred sheep populations which had CGEs comparable to the populations used in the present study (Rochus and Johansson, 2024, … WebThe inbreeding coefficient can have any value between 0 and 1.0, although it is unlikely for it to have a value much above . 5 in most herds of livestock. These coefficients are relative to a particular population. It is fairly easy to have it approach 1.0 in plant species where self-fertilization is possible. photo prints mailed to me
