It was realized in the 1940s that DNA is passed down thru generations of breeding. DNA strands contain information in sequential codes which combined with environmental factors determine physical traits, behavioural characteristics and the possible predisposition for potential health issues. DNA extracted from your dogs cheek cells presents genetic sequences which are linked to historical data on breeds and their traits accumulated over many generations.
