An example of an analogy used by a scientist to explain science:
"The reality is that while we know about certain genetic variants, the vast majority of genetic variants that are influencing physical performance are as yet unknown. I think it would be wrong to make a conclusion about an individual's potential based on genetic tests, given the current state of knowledge. It's like looking at a jigsaw with, I don't know, six pieces in, but it's 500 pieces, and trying to make conclusions about what the picture is at the end. I don't think you could do that realistically."
Prof. Alun Williams, Professor of Sport and Exercise Genomics at Manchester Metropolitan University, was talking on an episode ('Be More Athlete') of BBC's 'Curious Cases'.
