| WHAT HAPPENS ELSEWHERE? Australia - Embryos allowed to be created for research, but human-animal hybrids banned. The only exception is to test the quality of spermCanada - Legislation bans the creation of human-animal embryosUS - Federal funds can only be used for research involving pre-existing embryos - such as those left over from fertility treatment - and there is a ban on hybrid embryosElsewhere - Other countries do not specifically legislate on hybrid embryos. But Italy and Germany only allow the use of pre-existing embryos and many others including Austria, Norway and Tunisia do not allow embryo research at all | |
| Scientists want to create hybrid embryos by merging human cells with animal eggs in a bid to extract stem cells. The embryos would then be destroyed within 14 days. | Scientists want to create hybrid embryos by merging human cells with animal eggs in a bid to extract stem cells.
