Coefficient of inbreeding sheep
WebInbreeding coefficients are calculated routinely for all animals included in national genetic evaluations for yield traits. The base population for inbreeding is defined as animals … WebInbreeding coefficient, COI, is a percentage of probability that the ram and ewe share a common ancestor that contributed a common gene. 0% COI indicates that there is zero probability that the sheep have a common ancestor; 80% indicates that the two sheep are very closely related and that genes from a common ancestor will continued on page 7 Ø
