title: Effect of hyperthermia upon gamma-ray induced crossing-over in an excision repair deficient male Drosophila melanogaster.
abstract: Hyperthermia of 1 h at 38 degrees C did increase gamma-ray induced crossing-over in meiotic cells of male larvae and adults. However, there was considerably less effect of the heat treatment upon radiation induced crossing-over (a chromosome breakage event) in an excision repair mutant y mei-9a.
