George Wishart - Dean of Medicine

"Is there one thing in genetics which is of any use to medicine?"

The development of the ascomycete fungus Aspergillus nidulans as a convenient genetical tool led to the discovery in 1950 with Alan Roper of asexual reproduction, the parasexual cycle, in fungi. The consequences are similar to what happens in sexual reproduction, crossing over and recombination of genes.

Independently he also recognised, that the parasexual cycle if studied in cell cultures would contribute to the knowledge of human genetics. He went on to explore the application of this methodology to the in vitro analysis of human heredity, in which it later played a key role.
