(i) transferring a non-primate mammalian donor nucleus from a diploid somatic cell into a first recipient oocyte;
(ii) removing the donor nucleus from the first recipient oocyte;
(iii) providing a second recipient oocyte or enucleated fertilized zygote; and
(iv) transferring the donor nucleus from the first recipient oocyte into the second recipient oocyte or the enucleated fertilized zygote to obtain a reconstituted non-primate mammalian embryo, wherein the second recipient oocyte is activated prior to, concomitant with or following transfer of the donor nucleus.
