Inbreeding 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 … WebIf you are planning to breed your mice, you should provide nesting material (tissue paper works well) in one corner of the cage. Females can have up to 15 litters a year and can become pregnant within 24 hours after giving birth. The average gestation time for mice is 19 to 21 days. Baby mice are called pups and are born deaf and blind.

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. WebC57BL/6, often referred to as "C57 black 6", "C57" or "black 6", is a common inbred strain of laboratory mouse .

WebMouse Breeding Recommendations 1. Keep accurate breeding records. Make a pedigree for each transgenic founder or embryonic stem cell-mouse chimera. 2. Mate mice when they are sexually mature (6 to 8 weeks old). We recommend that transgenic founders or chimeras be mated to C57BL/6 mice. Webvii. Litter size varies among strains, but averages 4-12 pups. Inbred mice tend to have smaller litters than outbred mice. viii. Mice are typically weaned at 21-28 days or at 10g of body weight. The Institutional Animal Care and Use Committee requires that mouse pups be weaned at 21 days unless IACUC approval is given on an approved animal use ... binary long division

WebInbred mouse strains have important differences in their behavioral and neuroanatomical characteristics, and in their susceptibility to neurotoxic insults (Schauwecker, 2002). Two commonly used inbred strains in transgenic studies are FvB and C57/BL6 (Watase and Zoghbi, 2003). Oocytes from FvB mice are relatively easy for pronuclear injection ...

Each strain within a RI set is equally likely to have inherited either the maternal or paternal progenitor strain allele at each autosomal locus.

WebHowever, at each subsequent filial generation, genetic homogeneity among siblings is slowly recovered in a process referred to as inbreeding. Eventually, this process will lead to the production of inbred mice that are genetically homogeneous and homozygous at all loci. WebInbred strains of mice are defined as strains that have been maintained by successive brother to sister matings over more than 20 generations (Green, 1975). Repetitive …

WebJan 17, 2024 · Because inbred mice are genetically identical, interindividual phenotypic variability can be attributed to experimental variables and to a lesser extent, epigenetic variation (Weichman and Chaillet 1997).
