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.
WebBreeding and Reproduction of Mice. Mice reach sexual maturity at about 6 to 8 weeks of age. From this age onward, females and males should be housed separately. If 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 ... Web1.1.2 Inbreeding. Inbreeding is defined as the probability of two alleles in an individual being identical by descent, and is normally the result of mating related individuals. The rate of inbreeding is a function of the characteristics of the foundation stock as well as limited population sizes in subsequent generations (Falconer, 1989 ).
