WebJan 17, 2024 · However, 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 seek to model such variation. In contrast to inbred strains, outbred stocks exhibit interindividual variation and heterozygosity, coupled with higher fecundity. WebInbred and outbred nude mice? An inbred strain is one that: Is produced using at least 20 consecutive generations of sister x brother or parent x offspring matings, or; Is traceable to a single ancestral pair in the 20th or subsequent generation.
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. WebInbreeding can negatively affect various fitness components. Here we examine how immune response and body size of a social insect are affected by inbreeding, sex and ploidy. 2. In the bumble-bee, Bombus terrestris (L.), the offspring of colonies resulting from brother–sister matings were compared with that of outbred colonies. Immune response
WebA Inbred Strains Rats have been used as research models for more than 150 years. Many rat models of human disease were developed through breeding strategies aimed at selecting rats with divergence in phenotypes and selectively inbreeding these rats.
