Genetic Technology (Precision Breeding) Bill

Debate between Lord Krebs and Lord Winston

Report stage
Wednesday 25th January 2023 Lords Chamber

[Lord Krebs (CB)]

Obviously, I agree that the different parts of the genome serve different functions. As the noble Baroness said in Committee, when we were students, we learned about junk DNA. However, it is not junk DNA; it can play an important part in regulating the expression of other genes. I take the point.

[Lord Winston (Lab)]

I love the idea of the noble Lord’s field of wheat waving gently in the breeze and the sunlight, but does he not agree that certain genes in those wheat seeds are rather well conserved and, in fact, do not change? Indeed, certain genes are protected from mutation. Therefore, there is nothing to prevent us looking at analysis to see the frequency of certain mutations within the genome; perhaps we need to be doing that. The data there could be very useful in all sorts of ways.

My Lords, I join my noble friend Lord Trees in welcoming the inclusion of animals in this Bill, but I have added my name to Amendment 6, which would restrict the animals in question in the first instance to those involved in agriculture. My main reason for proceeding cautiously relates to the point just raised by the noble Baroness, Lady Jones of Whitchurch, of public acceptance. There is a risk that, if the net is cast too wide with the inclusion of animals, there could be a backlash, which would undermine the whole endeavour.

As the noble Baroness, Lady Bennett of Manor Castle, has said, Amendment 5, which excludes companion animals, is a helpful start. I agree with her that many people would be horrified at the thought that we might breed dogs with further flattened noses through gene editing and that they would suffer the consequences of that.

One can also ask: would the public be happy to see gene-edited wild animals? We discussed that in relation to plants a few minutes ago. One could conjure up examples where the answer might be yes. For instance, if we could gene-edit herring gulls to stop them stealing ice creams and chips at the seaside, that might perhaps be a popular move; but I suspect that, on the whole, people would not be happy to see our native animals gene edited outside the context of agriculture. As it is most likely that the early applications of gene editing in animals will be for agriculture, why not acknowledge this, start here and progress step-wise to widen the range of animals at a later stage if that is deemed advantageous?

The advantage of Amendment 6 over Amendment 8, which refers to farmed animals, is that Amendment 6 would allow for the gene editing of, for instance, a pest or parasite of an agricultural species while Amendment 8 would not. I defer to the noble Lord, Lord Trees, for his expertise on this, but it may in some circumstances be easier to reduce the burden of disease on farm animals by altering the genome of the disease-causing organism rather than the genome of the farmed animal itself.

So, while I am in favour of including animals in the Bill, I think there is a case for proceeding cautiously and, in the first instance, restricting that to agricultural contexts.

[Lord Winston (Lab)]

My Lords, Amendment 9 is in my name. I will be very brief about that, but I agree that we should be extremely cautious generally about animals at this stage. There is a lot of concern. From the example of dealing with pigs in a genome environment, I know that they are very different from some of the other mammals that we have been experimenting with. We may come to that issue later on when it comes to licensing.

With regard to Amendment 9, there is a strong case as well for limiting this to farm animals, if we go ahead at all—and if we do I would like to see equines excluded, for pretty obvious reasons. Some time ago, when I was working with an anaesthetist who was looking at equine metabolism, it was amazing how suspiciously the horse-breeding industry looked at our work—so much so that we could not share our data on their metabolism. It was very clear that we would have great difficulty with the restrictions that are proposed on that industry.

With regard to the great apes, it would be wrong to consider them in the same way as other mammals. It seems to me that these sapient creatures are so close to humans that they ought not to be included in the Bill. There are restrictions, of course, on the use of rhesus monkeys in research. I have worked with rhesus monkeys, not in Britain but in the United States. As a research worker, I always found that extremely distressing because I saw their response to even just a visit from us, when they knew we were going to do something which they thought would be unpleasant. I feel strongly that there has to be a very strong case for modifying sapient creatures, perhaps even to make them less sapient—so I propose Amendment 9 on that basis.
