mortality/aging
• 50% fewer than expected blastocysts are recovered at E3.5
• however, the number of 2 to 8 cell staged mice is normal

embryo
• first and second polar bodies are retained within fertilized oocyte and results in multi-pronuclei at the 1-cell stage
• anaphase chromosome compaction results in the formation of multinucleated cells during oocyte meiosis II and early embryogenesis

• anaphase chromosome compaction results in the formation of multinucleated cells during oocyte meiosis II and early embryogenesis
