While experimenting in 1948, Geneticist Hannes Laven of the Johannes Gutenberg University in Mainz discovered that common mosquitoes from Paris that were mated with members of the same species from Hamburg would not produce offspring. The reason for this sterility, he determined, was a difference in the cytoplasm (the protoplasm surrounding the cell nucleus) between the Paris and Hamburg strains of mosquitoes. Because of this difference, the egg cells of the females of one strain could not accept the sperm cells from males of the other strain, causing the female to lay infertile eggs. This Franco-German incompatibility...

...Geneticist Maimon J. Cohen and his colleagues were making a highly preliminary report. They had found this phenomenon in the blood of only three people. From two healthy subjects they drew blood, then grew the white cells in the test tube. When LSD, in varying concentrations, was added for durations of four to 48 hours, the number of broken or otherwise damaged chromosomes was increased as much as tenfold over the small number usually found in healthy cells...

...trust to luck, worry throughout the pregnancy, and blame themselves if a defective child was born. The other was to have no child. Now, by using charts of probabilities worked out by Dr. J. A.
