  +                            As determined in IMPReSS (see interactive diagram <a href="${cmsBaseUrl}/impress">here</a>), all embryonic lethal lines undergo
  +                            gross morphology assessment at E12.5 (embryonic day 12.5) to determine whether defects occur
  +                            earlier or later during embryonic development. A comprehensive imaging platform is then used
  +                            to assess dysmorphology. Embryo gross morphology, as well as 2D and 3D imaging are actively
  +                            being implemented by the IMPC for lethal lines.

                      <p>Each IMPC gene knockout strain is assessed for viability by examination of litters produced from
                          mating heterozygous animals. A strain is declared lethal if no homozygous nulls pups are
                          detected at weaning age. A strain is declared subviable if homozygous null pups constitute less
                          than 12.5% of the litter. For lethal strains, embryos are phenotyped in the embryonic and
                          perinatal lethal pipeline. For embryonic lethal and subviable strains, heterozygotes are
                          phenotyped in the IMPC adult phenotyping pipeline.</p>
