Inbreeding*. Male. Pedigree. United States. The estimate of inbreeding for registered Holstein females born during 1990 was 5.1 +/- 0.4% for a random sample of 600 two-line pedigrees. Previously published estimates were 4.7% for 1970, 3.8% for 1976, and 4.3% for 1982 from similar samples of pedigrees. These estimates were calculated using a b ….

Inbreeding commonly leads to inbreeding depression, the reduced fitness of individuals due to deleterious recessive (or partially recessive) mutations exposed in the homozygous state [8,9].

In clinical genetics, a consanguineous marriage is defined as a union between two individuals who are related as second cousins or closer, with the inbreeding coefficient (F) equal or higher than 0.0156 (Bittles 2001), where (F) represents a measure of the proportion of loci at which the offspring of a consanguineous union is expected to inherit identical gene ...The inbreeding depression parameter (F(1−F)H* Figure 7k) is 0 for or F=1 and reaches its maximum at F=0.5 and equal allele frequencies. To sum up, we showed how inbreeding affects heritability of heterozygosity in randomly mating populations and in populations where all individuals are experimentally inbred to the same level.Fertility rates are affected by inbreeding, and already, Holstein fertility has dropped significantly. Pregnancy rates in the 1960s were 35 to 40 percent, but by 2000 had dropped to 24 percent.1. Introduction. Mating with relatives (inbreeding) can result in offspring with reduced survival and fertility, a phenomenon known as inbreeding depression [].Inbreeding depression has been observed to occur in wild animals with severe consequences [2,3].This has led to the prediction that selection will favour individuals that base mate choice decisions on relatedness [2,4-7].Inbreeding.
