Description:
Several dysgenic traits may occur within the Drosophila melanogaster species as a result of crosses between different strains. Crossing two mutually interacting categories, named inducer and reactive, may lead, among other abnormalities, to a specific kind of female sterility that has proved useful for investigating the genetic factors involved in the interaction. The reactive state appears to result from a cytoplasmic state ultimately controlled by a chromosomal polygenic system. The inducer character is determined by a chromosomal factor that exhibits all characteristics of a transposable element. Overall, the data contribute to clarification of mutator activities in D. melanogaster and open new opportunities to investigate unusual genetic mechanisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bregliano, J C -- Picard, G -- Bucheton, A -- Pelisson, A -- Lavige, J M -- L'Heritier, P -- New York, N.Y. -- Science. 1980 Feb 8;207(4431):606-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6766221" target="_blank"〉PubMed〈/a〉
