WebJan 4, 2016 · The big difference between inbred mice and dogs or tigers is the "for specific phenotype" aspect. Laboratory organisms are inbred so that you get a large pool of genetically-identical individuals, meaning they're much easier to experiment on. The aim is the inbreeding itself, not any particular phenotype.
