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.
γ射线诱发斑马鱼(Brachydanio rerio)特定基因座和隐性致死突变的频率分别约为 4×10-5 r-1和 4×10-3 r-1,符合一级动力学。隐性致死突变与特定基因座突变的比值(100:1)出人意料地低,这可能是由于γ射线诱导了大的缺失。
