DNA-DNA hybridization studies lead us to believe that about 98.9 percent of the chimpanzee and human genomes are identical in nucleotide composition. I found this in Evolutionary Biology by Doug Futuyma (p. 510) and his reference was a 1975 article by M. C. King and Allan Wilson from the journal Science, vol 188, pages 107-116. Futuyma didin't say, but I am assuming this is Pan troglodytes, the common chimpanzee, and not Pan paniscus, the bonobo. Some recent work (I don't have a reference, it may have actually been an episode of Nature on PBS) has suggested that H. sapiens may actually be more closely related to P. paniscus rather than P. troglodytes, so the figure quoted above may or may not be accurate, but it's probably close enough for most purposes.
