WebInbred strains are defined as the product of 20 consecutive generations of brother–sister matings. Under these conditions, it has been calculated and now observed that the probability of homozygosity (genetic identity between the two alleles of … 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 …
Common Laboratory Mouse Strains: A Beginner
WebThe outbred stocks are used most commonly in safety testing. Sprague Dawley (SD) rats are an outbred stock originally developed from Wistar rats crossed with a variety of other laboratory and wild rats. Long–Evans rats are utilized occasionally for reproductive, behavioral, and dietary studies. WebJan 10, 2024 · Inbred mouse strains have been used preferentially for behavioral testing over outbred counterparts, even though outbred mice reflect the genetic diversity in the human population better. Here, we compare the sociability of widely available outbred CD1 mice with the commonly used inbred C57BL/6J (C57) mice in the one-chamber social … cif fireprotect
What is the difference between inbred and outbred mice?
WebTherefore, in this study, we initially screened the inbred and outbred mouse strains based on exploratory behavior toward new environments (i.e., Y-Maze spontaneous alternation), a learning and memory task (i.e., passive avoidance test), and variation in cholinergic system (acetylcholinesterase activity) at the hippocampus. 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 … WebHowever, inbred strains do not recapitulate the extent of interindividual variation found in a human cohort, patient group, or population making them inappropriate for studies that … dharman christmas
