Studies in mice show it is possible to prevent the transmission of mitochondrial disease by moving the pronuclei - the genetic material which will go on to form a nucleus - from a fertilised egg containing bad mitochondria and putting it into another fertilised egg which only contains good mitochondria ...

At the commencement of the segmentation process the chromosomes of the two pronuclei group themselves around the equator of the nuclear spindle and then divide; an equal number of male and female chromosomes travel to the opposite poles of the spindle, and thus the male and female pronuclei contribute equal shares of chromatin to the nuclei of the two cells which result from the subdivision of the fertilized ovum.

Again, it has been observed, in some of the lower animals, that the pronuclei do not fuse but merely lie in apposition.
