Inbreeding in mice

WebThe process of inbreeding becomes understandable when one realizes that at each generation beyond F 1, there is a finite probability that the two siblings chosen to produce the subsequent generation will be homozygous … 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.

If this happens generation after generation, the population of mice becomes inbred, which means they’re kind of like clones of one another. In this case, inbreeding can result in smaller litters.
