【摘要】 用C.S.,Basc和bw-st/bw-st三种系统的果蝇研究了氦-氖激光、氮分子激光和氩离子激光辐射对果蝇遗传的影响。实验结果表明,当氦-氖激光辐照剂量达32J/cm~2,氮分子激光辐照剂量达0.75J/cm~2,氩离子激光辐照剂量达196J/cm~2时,尚未发现隐性致死突变或易位的遗传效应。更多还原

【Abstract】 The genetic effect of three stocks of D. melanogaster, C. S., Base, and bw-st/bw-st were studied with irradiation from He-Ne, nitrogen and argon ion lasers. Experimental results show that when the radiation dosages of He-Ne laser, nitrogen laser and argon ion laser amounted to 32J/cm3, 0.75J/cm2 and 196J/cm2, respectively, genetic effects of recessive lethal mutation and translocation have not been observedyet.更多还原
