WebThe challenge in breeding outbred animals is to maintain the diversity at the level of the individual, yet somehow standardize multiple production colonies of these animals that are geographically separated so that each colony has the same range of genetic variation. WebApr 25, 2024 · Inbred and outbred offspring differed in their survival when challenged with pathogens (P = 0.001), with inbred offspring exhibiting a higher mortality rate than those from outbred pairings (Fig. 5b).
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. WebInbred and outbred nude mice?
