Human Fertilisation and Embryology Bill [HL]

My Lords, I think I am in order in using this opportunity to suggest to my noble friend that he might elicit from the Minister a clarification of a little sentence he put in that could be quite important. He said that predominance would not depend upon percentage only but also on location or function. Could my noble friend ask the Minister whether that means that if the cells concerned relate to the brain, which is the example he gave, although they are less than 50 per cent, they still predominate?
