WebFor instance, a few strains of highly inbred animals may be best for identifying the function of a specific gene, while a highly outbred population that captures much of the natural … WebOutbred rat models are used in preclinical research to mimic genetic variation in humans. Since human diseases are genetically linked, these models can help researchers understand how certain genetic variations contribute to disease. Outbred models are less susceptible to environmental differences, but are as phenotypically stable as inbred ...

Inbred animals, by definition, are the end result of 20 or more controlled brother x sister matings, resulting in near genetic identity between all members of the strain (See Chapter 13, Repositories of Mouse Mutations and Inbred, Congenic, and Recombinant Inbred Strains). Because inbred mice can be raised in a …
WebJan 1, 1994 · The inbred strain types are characterized by a high isogenicity - the strain members are genetically identical and homozygous at almost all loci (possibly with a forced heterozygosity at a single locus). The genotype of an inbred strain arises from an accidental fixation of alleles from the heterogeneous starting-population, so the animals of an inbred … WebDec 20, 2014 · In the study of 66 outbred stocks (Yalcin et al. 2010), the level of heterozygosity per locus, which is zero in inbred strains, ranged from 0.01 to 0.34 in outbred stocks with 4 stocks found to be nearly inbred and a further 5 quite inbred. Six of the colonies were resampled after a year, and one was found to have substantially changed …
WebInbreeding eliminates the genotypic variation between individuals of a specific strain. Inbred animals are therefore preferable in many experimental studies as their genotype is … WebDiversity Outbred mice were generated by breeding eight founder inbred strains together to produce a population with a random assortment of genetics (Figure 2). The eight founder strains were chosen specifically because of their unique characteristics. For example, one develops type 1 diabetes (NOD/ShiLtJ), another is prone to cancer (A/J), and ...
WebInbred mice are preferred over outbred mice with the assumption that they display less trait variability. We compared coefficients of variation and failed to find evidence of greater trait stability in inbred mice. We conclude that contrary to conventional wisdom, outbred mice may be better subjects for most biomedical research.
