Genetic Blueprints. To map the chimp genome, researchers used DNA from the blood of a male common chimpanzee (Pan troglodytes) named Clint, who lived at the Yerkes National Primate Research Center in Atlanta. Clint died last year from heart failure at the relatively young age of 24. A comparison of Clint's genetic blueprints with that of the human genome shows that our closest living relatives share 96 percent of our DNA.
It is the percentage of DNA in common for human and other organisms .for example,banana shares 50%of DNA with humans,where rat shares approx about 75%,,..I think so, and chimpanzee shares 98%,with our humans we have 99.9% of same DNA sequence ,,the huge difference occurs within our humans lies in the remaining 0.1%
