| The first two varieties cross-fertilize satisfactorily, as do the last two. |
| They distribute insights and ideas rapidly and cross-fertilize ideas to encourage innovation. |
| Ethnomusicology has continued to cross-fertilize in intra and interdisciplinary ways. |
| Botanists have classically viewed this polymorphism as an outcrossing mechanism, since in most situations reciprocal morphs can only cross-fertilize. |
| Physid snails usually cross-fertilize but are capable of occasional self-fertilization. |
| First, do the different organizations that are discussed in the various chapters cross-fertilize one another? |
