ABSTRACT. Inbreeding coefficients are calculated routinely for all animals included in na- tional genetic evaluations for yield traits. The base population for inbreeding is defined as animals born during 1960.The offspring resulting from inbreeding tend to have health problems and lower reproductive success. This is known as inbreeding depression. Inbreeding depression occurs because of a quirk of natural selection and genetics.
