Inbreeding coefficient pdf
Webfairly easily once inbreeding coefficients are calculated. Algorithms to construct relationship inverses (A−1) can either ignore parent inbreeding, resulting in an approximate inverse (A 1 0 −), or include parent inbreeding, providing an exact A−1. Assumed genetic variance and bull rankings were only slightly affected by use of A 1 0 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 ...

WebAn inbreeding coefficient of 25% would equate to the genetic equivalent of a dog produced from a father to daughter mating. Inbreeding can be accumulative and so if it has occurred to a significant degree over several generations, the inbreeding coefficient may exceed 25%.
