Genetic engineering appears to offer potential
health benefits but also raises many moral issues.
Did you know?
98% of cloned animals have genetic deformities.
Cloning humans is likely to have the same effect.
Scientists hope that stem cells can be used to
help people with incurable illnesses and disabilities but we do
not need to use embryos or create clones to do this; there are
other sources.
PGD tests embryos, created by IVF, for genetic
disabilities or to select a tissue match to treat an older sibling
with a disability.
In Britain research may be carried out on human
embryos up to 14 days after conception. After 14 days they must
then be destroyed.
