That is, an animal was scored as unimpaired if it did not have any visible defects in motility or tissue morphology; an animal was scored as impaired if it had defects in motility or tissue morphology.
These matings produced fairly normal litter sizes (average 7.4 pups/litter), and the CKO mice from these litters (Tek floxed/floxed genotype) were viable, without any visible defects (Figure 1A left).
