Abstract

Using heterozygosity for bw mutations, the frequency of somatic mosaicism has been studied in Drosophila melanogaster flies, homozygous for radiosensitive mutation, rad(2)201G1, and in those not carrying the mutation. Data obtained for control and after irradiation of larvae with 150, 450 and 750 R showed that homozygotes for the rad(2)201G1 were characterized by elevated levels of both spontaneous and induced mosaicism.

摘要

利用bw突变的杂合性，对黑腹果蝇中对辐射敏感的突变体rad(2)201G1纯合子以及未携带该突变的果蝇中的体细胞镶嵌现象频率进行了研究。对照以及用150、450和750伦琴（R）照射幼虫后所获得的数据表明，rad(2)201G1纯合子的特征是自发和诱导镶嵌现象的水平均有所升高。
