Human Fertilisation and Embryology Bill [Lords]

I think that there is a very big difference between a cell that has a 51 per cent. animal and 49 per cent. human make-up and one that has a 99 per cent. human make-up. That is, of course, what we are debating today and it is the issue on which the House must make up its mind. There is a also a significant difference between the transfer of genes and chromosomes and the mixing of gametes, which are sex cells. I hope that the Minister will be able to clarify some of the issues we have raised. I await to hear her response before deciding whether to put these amendments to the test later.
