Inbreeding in mice
WebVariation in response to fescue toxicosis was examined in inbred and linecross mice. In Exp. 1, exposure to a 50% endophyte-infected tall fescue diet (E+) reduced ADG of males from six inbred lines, but ADG of males from one line was modestly higher on E+. Lines differed (P < .01) for reproductiv … WebDec 10, 2007 · Mouse populations are known to persist at high densities for extended periods of time (Bronson 1979), and during population outbreaks house mice are subject to inbreeding (Sutherland et al. 2005). Therefore, because there are significant fitness consequences of inbreeding in mice ( Margulis 1998 ; Meagher et al. 2000 ), selection …

WebWhen inbred mice are immunized with certain antigens, particularly synthetic peptides or proteins that closely resemble self, it is found that some strains respond and others do not ( Benacerraf and McDevitt, 1972 ). The genes responsible were found to be encoded within the MHC, and have been termed Immune Response (Ir) Genes.
