title: Histological analyses of lethal yellow mouse embryos (Ay/Ay) at 90 and 132 h post coitum.
abstract: Strain C57BL/6J-Ay/Ay embryos are developmentally retarded in utero at 90 hpc and are resorbed by 132 hpc. The Ay/Ay developmental delay previously observed in vitro has now been confirmed in vivo. Apparently Ay is involved in some aspect of cleavage stage metabolism.
