For the captive population, the average pedigree-based inbreeding coefficient was F Ped_5gen =0.013. However, pedigree founders were already related by an average F Ped_18gen of 0.030 ( Forstmeier et al., 2004 ). Thus, the birds from our captive population had an F Ped_23gen of approximately 0.030+0.013=0.043.The coefficient of inbreeding is the probability of inheriting two copies of the same allele from an ancestor that occurs on both sides of the pedigree. These alleles are "identical by descent". The inbreeding coefficient is also the fraction of all of the genes of an animal that are homozygous (two copies of the same allele).

The two studies showed that reduced genetic diversity and inbreeding was associated with a reduced risk of breast, skin, thyroid and female genital cancers, but an increased risk of developing leukaemia, lymphoma, colorectal and prostate cancer [61,62]. The incongruous results observed in some human studies suggest that the effect of genetic ...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 reduces the size of the gene pool, which can lead to problems such as decreased genetic variability and the persistence of potentially harmful mutations, making it harder for the remaining population to adapt to changes in their environment. In a very small population, any mutations that occur are much more likely to be passed on to ...Inbreeding depression can also be generated by epistasis between dominance effects across loci, such that favorable gene combinations among heterozygous genotypes decrease in frequency during the inbreeding process (Jain and Allard, 1966).

Breeding systems serve to promote and preserve desired genetic traits in a breed or species. Over the past centuries, humans have developed several breeding systems (e.g., pure-breeding, inbreeding, crossbreeding). Each breeding system has unique benefits, and the use of different techniques may lead to different outcomes.In the United States, incest is illegal in all 50 states.

We have investigated the effects of inbreeding on fertility among inbred adult Hutterites and demonstrate significantly reduced ...The slopes of these lines tell us exactly what this "cost-benefit" ratio is. For these breeds, those slopes are about 0.1, which means that an increase in inbreeding of 10% reduces litter size by about 1. If normal litter size is about 6, a COI of 30% - which is not uncommon in many breeds - would reduce the litter size by HALF.
