One species, many genomes

.... Almost every tenth gene was so defective that it could not fulfill its normal function anymore! Results such as these raise fundamental questions. For one, they qualify the value of the model genomes sequenced so far. "There isn’t such a thing as the genome of a species," says Weigel. He adds "The in...
