Studying Genetically Altered Mice in Behavioral Genetics :: Behavioral Genetics

The field of mien genetics is rapidly expanding. The practice of altering genes in mice and observing the effects is very common. Because of this it would be appropriate to adopt specific tests which will certify the behavioral phenotype of the organism. In test for the effects of genetic alteration it must first be ascertained that all of the necessary genotypes are represented. These complicate homozygous and heterozygous mice and wild type mice with no genetic alterations as controls. If significant differences are found between male and female mice the twain sexes must be evaluated on their own. Care must also be taken in selecting the right strain of mice. This is because it has been found that in the strains that are usually used for testing some behaviors are noted to be aberrant and the unusual behavior in these genes might lead to the misapprehension of the studied mutation. Different approaches are used in order to rent 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 health are obtained by arranging the mouses weight, temperature, and any abnormal features. Neurological function is because assessed using different types of tests. The mouse is stimulated to see if it reacts normally to discordant different types of stimuli. Reflexes are measured by seeing how the animal reacts to a moving surface, light, and touch. The mouse is then observed in an area resembling an uncovered 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 distance between them. The hearing cleverness of mice is also measured.These tests can help demonstrate the behavioral paradigms for the animal that is creation studied. In some cases a deficit 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 study the behavioral phenotype of the mice because of deficits in their functioning.
