Frequency of gamma-Ray Induced Specific Locus and Recessive Lethal Mutations in Mature Germ Cells of the Zebrafish, BRACHYDANIO RERIO.
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.
