From the large number of strains of mice, successfully propagated for more than 20 generations and some for more than 100 generations of brother-sister inbreeding, one may gain the impression that mice accept inbreeding easily. Two observations First, many attempts to inbreed mice have failed.
WebDec 13, 2024 · To provide further context for our estimates of nucleotide diversity (π), we also retrieved recently published diversity metrics from house mice in the Collaborative Cross (Srivastava et al. 2024), various inbred and wild-caught mouse colonies (Salcedo et al. 2007), and inbred and wild-caught rats (Smits et al. 2004; Ness et al. 2012). WebMice used in lab experiments are often inbred, as the similar genetic structures enable experiments to be repeated. Controlling outcomes is also the motivation for inbreeding in …

We find that the major axis of genetic variation in M. m. domesticus is a south-to-north gradient within Europe and the Mediterranean.
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.
