Relevant experiments have been done in mice by a number of groups.  It is
possible to recognize male and female pronuclei in fertilized eggs.  If
male pronuclei are removed and replaced by a male pronucleus from another
fertilized egg and the surgically treated egg implanted in a surrogate
mother, it results in viable offspring.  However, combinations of two
female pronuclei or two male pronuclei don't work.  Neither do
combinations of a female pronucleus and the 2nd polar body.  It may be
related to genetic imprinting.
