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 ... WebAbstract. Inbreeding and its consequences are the main subject of Chapter 3, beginning with the concepts of identity by descent versus identity by state, the inbreeding coefficient F, genotype frequencies with inbreeding, and calculation of the inbreeding coefficient from pedigrees. Inbreeding and heterosis are discussed along with the effects ...
