I recall, from way back in my undergraduate days 1980-84, reading
about and discussing this topic during an embryology course. As I recall,
sperm from most organisms is able to penetrate and fertilize eggs from a
range of other species. This fertilized egg progresses through several
cell divisions, but usually dies fairly quickly. I suspect that this is due
to the inviability of certain chromosome rearrangements.
