One plus one makes more than two

Abstract

Pleasant memories rejuvenate and this letter is written to that purpose. Although dedicated to Barry Ganetzky, I hope it will please also those that shared their times with us in the lab of Seymour Benzer. For those too young to have so distant memories, I hope this text will teach them the same lessons we learnt then.

Keywords:

• Drosophila
• double mutants
• epistasis
• Nobel laureates

Acknowledgements

To the best of my knowledge, all events described here are faithful recollections from the period 1978?1981 at the lab of Seymour Benzer in Caltech. I am grateful to all lab members at that time, in particular to Barry Ganetzky to whom this letter is dedicated.

Have a big ‘abrazo’
