Dr Andrew Shelling from the University of Auckland talks about the importance of thoroughly examining the physical characteristics of their patients before they start to study the genetic sequences, or the , of the patients. Later, computers are used to look for patterns between physical characteristics (the ) and genetic characteristics (genotype).
