Description:
When the germ line of Drosophila males is destabilized by a syndrome known as hybrid dysgenesis, X-chromosome rearrangements are found in up to 10 percent of the gametes produced. Some of these aberrations are simple inversions, but many are complex multibreak rearrangements. Furthermore, most of the breakpoints fall into a few highly localized positions on the chromosome. These positions are mostly at points of intercalary heterochromatin and may vary from one strain to the next. the results suggest that they may represent points of insertion of mobile DNA sequences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berg, R -- Engels, W R -- Kreber, R A -- GM 07131/GM/NIGMS NIH HHS/ -- GM 22038/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1980 Oct;210(4468):427-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6776625" target="_blank"〉PubMed〈/a〉
