| The heterostyled plants are normally dependent on a process corresponding to hybridisation. |
| In most of the Mediterranean, one or both species occur, with some degree of hybridisation. |
| The University of Edinburgh found that, in Scotland, there has been extensive hybridisation with the closely related sika deer. |
| Whereas the effects of hybridisation could be forecast, creolisation is unpredictable. |
| A major success in the investigation of causes of congenital heart disease comes from molecular cytogenetics and the use of chromosome fluorescent in situ hybridisation. |
| Such hybridisation is very rare in the wild, and typically only occurs where European minks are declining. |
