Abstract

Specific locus and recessive lethal mutations are induced by γ-rays with approximately first order kinetics in the zebrafish (Brachydanio rerio) with frequencies of 4 × 10^-5 r^-1 and 4 × 10^-3 r^-1, respectively. The surprisingly low ratio (100:1) of recessive lethals to specific locus mutations may be due to the induction of large deficiencies by γ-rays.
