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. 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 …
