WebAug 31, 2024 · For over a century, inbred mice have been used in many areas of genetics research to gain insight into the genetic variation underlying traits of interest. WebMost RI strain sets result from randomly mated pairs of F2 mice followed by at least 20 generations of inbreeding. Each strain within a RI set is equally likely to have inherited either the maternal or paternal progenitor strain allele at each autosomal locus.
