The end result of the migration of the male and female pronuclei is their
juxtaposition. When adjacent, the pronuclei become associated in a
characteristic fashion to establish the genome of the embryo and conclude the
process of fertilization ...

In such situations, MEP of the affected zygotes could restore the pronuclei
constitution of the zygote to the diploid or normal stage. The doubt that arises is
whether or not MEP is completely safe. In animal studies, Feng and Gordon12

The resulting paternal pronuclei generally replicate more quickly than maternal
pronuclei [63, 64], which inherit a full set of histones from the oocyte [52, 61],
including the more common histone H3.1 [65]. Paternal pronuclei also differ from

It is important to note that during this process a zygote nucleus is not formed, i.e. ,
the pronuclei do not fuse. The maternally and paternally derived genomes are
associated within a single nucleus for the first time in the blastomeres of the ...
