2. 2 February, 2007 Genomics “The genetic blueprints of all people generally have the same information, with approximately 99% of one human genome sequence being identical to all others. That makes the 1% of places in the genetic code that account for human variation very interesting…” Momentum Winter 2006-2007, DNA Rubic “Some geneticists have calculated the differences in human and chimpanzee DNA as just over 1%, some at 1.6%, and others at 1.8%.” Momentum Winter 2006-2007, What we learn from Chimpanzees
