FREQUENCY OF gamma-RAY INDUCED SPECIFIC LOCUS AND RECESSIVE LETHAL MUTATIONS IN MATURE GERM CELLS OF THE ZEBRAFISH, BRACHYDANIO RERIO

1 Institute of Molecular Biology, University of Oregon, Eugene, Oregon 97403

Specific locus and recessive lethal mutations are induced by gamma-rays with approximately first order kinetics in the zebrafish (Brachydanio rerio) with frequencies of 4 x 10-5 r-1 and 4 x 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 gamma-rays.
