本工作以黑腹果蝇为实验材料,采用Muller-5检测技术,进行了伴性隐性致死频率的卫星空间飞行试验。结果表明,卫星空间飞行的综合因素对果蝇伴性隐性致死频率变异有增高趋势。提示我们,空间飞行因素的遗传效应及其防护的研究仍是今后应重视的研究课题。 In this work, Drosophila melanogaster was used as experimental material, and the Muller-5 detection technique was used to carry out satellite space flight experiments with the frequency of recessive lethality. The results show that the integrated factors of satellite space flight have an increasing trend on the frequency of recessive lethality associated with Drosophila. We are reminded that the research on the genetic effects of space flight and its protection is still the research topic that should be paid attention to in the future.
