ANIMAL OUTBRED STRAINS Meaning and
Definition
-
Animal outbred strains refer to genetically diverse populations of animals used in scientific research and breeding programs. These strains are characterized by high levels of genetic variation, resulting from mating unrelated individuals over multiple generations. Unlike inbred strains, which are bred to be genetically identical, outbred strains maintain genetic diversity, similar to natural populations.
The purpose of using animal outbred strains is to model the genetic heterogeneity found in human populations, enabling researchers to study complex traits, diseases, and their interactions with the environment. By mimicking natural genetic diversity, outbred strains provide a more representative and realistic platform for understanding the genetic basis of phenotypic variation and the influence of genetic background on biological processes.
One of the advantages of animal outbred strains is that they allow researchers to investigate diseases and responses to therapies in a more comprehensive manner. The genetic heterogeneity in these strains better reflects the variability seen in human populations, thus enhancing the translatability of preclinical research findings. Furthermore, studying outbred strains can help researchers uncover novel genetic associations and interactions that may be missed when using inbred strains.
Animal outbred strains are commonly used in behavioral, pharmacological, and toxicological studies, as well as in assessing the efficacy of new drugs and therapies. By maintaining the genetic diversity inherent in natural populations, animal outbred strains serve as invaluable tools for advancing our knowledge of genetic and environmental interactions, and ultimately contribute to improving human health and well-being.
