Studying Genetically Altered Mice in Behavioral Genetics :: Behavioral Genetics

The field of demeanour genetics is rapidly expanding. The practice of mending genes in mice and observing the concur is very common. Because of this it would be appropriate to lard specific tests which provide lay down the behavioral pheno caseful of the organism. In testing for the effects of genetic alteration it must first be ascertained that every of the necessary genotypes are represented. These include homozygous and heterozygous mice and wild type mice with no genetic alterations as controls. If significant differences are found surrounded by male and female mice the two sexes must be evaluated on their own. wield must similarly be taken in selecting the right air travel of mice. This is because it has been found that in the strains that are usually utilise for testing about behaviors are noted to be aberrant and the unusual behavior in these genes might lead to the misinterpretation of the studied mutation. Different approaches are used in order to make the interpretation of these results more accurate in this sort of genetic background. When evaluating the behavior of genetically altered mice it must be ascertained that the mice dont show any signs of aberrant behavior which would make further testing difficult or impossible. Indices of general wellness are obtained by recording the mouses weight, temperature, and any unnatural features. Neurological function is then assessed using different types of tests. The mouse is emotional to see if it reacts normally to various different types of stimuli. Reflexes are accountd by seeing how the animal reacts to a moving surface, light, and touch. The mouse is then discovered in an area resembling an open field where its movements are recorded. Motor coordination is measure by placing it on a rotating rod and seeing how well it maintains its balance. This is also measures by recording its footprints in ink and measuring their pattern and the surmount between them. The hearing ability of mice is also measured.These tests can help demonstrate the behavioral paradigms for the animal that is being studied. In some cases a famine in motor or neurological function might make it impossible to run any further tests since almost all behavioral tests require certain basic functions such as locomotion. Sometimes the tests will have to be altered in order to effectively reflect the behavioral phenotype of the mice because of deficits in their functioning.
