Abstract
Partial sterility in 3 strains of malarial mosquito Anopheles atroparvus with heterozygous chromosomal rearrangements In2(R;L) 1+In2L1; In3(R;L) 1+D3R1; T(2R;3R)1 was studied. Fertility of these lines was decreased 2.5 to 5 times, as compared with the control. No homozygotes for rearrangements were detected. Causes for partial sterility of insects with heterozygous insertions, translocations and the significance of constructing homozygous strains are discussed.
摘要
对3株携带杂合染色体重排In2(R;L) 1+In2L1、In3(R;L) 1+D3R1、T(2R;3R)1的疟蚊按蚊atroparvus的部分不育情况进行了研究。与对照相比，这些品系的育性降低了2.5至5倍。未检测到重排的纯合子。讨论了具有杂合插入、易位的昆虫部分不育的原因以及构建纯合品系的意义。
