Values can range from −1 to +1. Negative numbers refer to outbreeding present in mating between individuals of different populations or less heterozygous than the population average.

WebIn the local breeds with small population size, one of the most important problems is the increase of inbreeding coefficient (F). High levels of inbreeding lead to reduced genetic diversity and inbreeding depression. Weba major reason. As shown in Figure 2, the inbreeding coefficient for US Holsteins and Jerseys has increased steadily from 1960 to 2007 (1960 is the ‘base’ year for U.S. inbreeding calculations; the inbreeding coefficient for animals born that year is assumed to be zero). Cattle have about 21,000 functional genes on 30 pairs of chromosomes.
