Diploid zygotes created by combining a male and a female pronucleus gave rise to viable embryos, but combining two male or two female pronuclei did not.
For instance, the migration of the male pronucleus within the animal oocyte after fertilization, together with movements of the female pronucleus , are essential events for nuclear fusion.
Transgenic mice were created by pronuclear injection as previously described.
In contrast, wisp embryos arrest after completion of meiosis II, before pronuclear fusion.
As noted previously, however, the most dramatic of all early nuclear migrations, pronuclear migration, occurred normally in all three mutant strains.
