“My name is Leslie. I’m a geneticist, and a good one. I had secretly worked for years on developing a virus that would swap every y chromosome in a male body with an x chromosome. Everyone in the genetics field had said that it was impossible, but that impossibility was what drove me to try and succeed. I had successfully made the gender swap with male rats. Then with several male chimpanzees, since they share 98.7% of their genetic material with humans. The transformations were complete, in that the males became fully female. The question was of whom to experiment with among humans.
