The presence of these organisms in a species and their absence in another causes the non-viability of the corresponding hybrid.

Such an admission of the non-viability of a security policy concept of this kind must surely encourage us to seek alternative concepts.

This indicates differentiation of the embryo development genes (or gene complexes) in these species and these differences determine the non-viability of the hybrids.
