WebThe coefficient of inbreeding ( F) is used to define the probability that two alleles will be identical and derived from the same forebear. The application of this principle is most … WebTherefore, an inbreeding coefficient over .5 is unlikely in a purebred herd of pigs. The general formula for an inbreeding coefficient is shown in figure 1. A common ancestor is an individual that appears on both the sire and dam side of the pedigree. Whenever a common ancestor is inbred, his/her inbreeding coefficient will have to be ...
