The year is 2045. The genomes of four billion humans have been sequenced, creating a huge pool of genetic information accessible to researchers.

But supporters of sharing genetic data argued convincingly that the benefits to society outweighed the privacy concerns of individuals. The debate may have once seemed abstract. But now you are in a fertility clinic and the issues are fast becoming real.
