WebJan 1, 2016 · The coefficient of inbreeding of the first generation of this population is also (1/2)N by definition of inbreeding. In each succeeding generation, the non-inbred part of the population will have a chance to produce offspring with an allele pair identical by descent. WebThe Table also gives the ‘Co-ancestry Coefficient of Progeny’ for each stallion/mare pairing. This is the level of inbreeding that the resulting foal would have. The lower this coefficient, the less inbred the foal would be. Co-ancestry coefficients of below 0.05 are considered acceptable whereas those of 0.05 and above are not. 4.
