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.
Children share 50% of their DNA with their mother and the other 50% with their father. Aunts and Uncles share around 25% of their DNA with their nieces and nephews. when it comes to first cousins, they will share a maximum of 13% of their DNA with each other.
