title: Revelling in cytogenetics.
abstract: A fascination with chromosomes, especially chromosomal aberrations, linked many at the Oak Ridge National Laboratory and the Medical Research Council Radiobiological Research Unit at Harwell, but they disagreed about the correctness of Revell's exchange hypothesis. This is a personal story of how a critical test of this hypothesis was conceived, with glimpses of life in the two centres.
