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.
In general you share an average of 50% less DNA with an ancestor with each additional generation. To calculate how much DNA you are likely to share with a cousin, you have to consider that they have also inherited 50% less DNA with each generation. This can be shown using a modified version of the genealogical relationship chart. For example, you and your relative share a common ancestor, Emmet Blacksheep.
