Rex:(1) is close to or in the basal heterochromatin of the Xchromosome; (2)is semidominant and (its effect) is temperature sensitive; (3) acts maternally; and (4) affects behavior of paternally derived attached-XY chromosomes shortly after fertilization. Though, at this point, the existence of Rexis known only from its effects on behavior of a particular compound chromosome, it presents intriguing possibilities for understanding regulation of chromosome behavior and organization of the ribosomal cistrons.<\/jats:p>","DOI":"10.1093\/genetics\/99.3-4.443","type":"journal-article","created":{"date-parts":[[2021,4,22]],"date-time":"2021-04-22T16:41:57Z","timestamp":1619109717000},"page":"443-459","source":"Crossref","is-referenced-by-count":7,"title":["GENETICALLY INDUCED MITOTIC EXCHANGE IN THE HETEROCHROMATIN OF <i>DROSOPHILA MELANOGASTER<\/i>"],"prefix":"10.1093","volume":"99","author":[{"given":"Leonard G","family":"Robbins","sequence":"first","affiliation":[{"name":"Genetics Program and Department of Zoology, Colleges of Natural Science and Osteopathic Medicine, Michigan State University, East Lansing, Michigan 48824"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[1981,11,1]]},"container-title":["Genetics"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/genetics\/article-pdf\/99\/3-4\/443\/34436400\/genetics0443.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/genetics\/article-pdf\/99\/3-4\/443\/34436400\/genetics0443.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,4,22]],"date-time":"2021-04-22T16:42:29Z","timestamp":1619109749000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/genetics\/article\/99\/3-4\/443\/5995002"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1981,11,1]]},"references-count":0,"journal-issue":{"issue":"3-4","published-print":{"date-parts":[[1981,11,1]]}},"URL":"https:\/\/doi.org\/10.1093\/genetics\/99.3-4.443","relation":{},"ISSN":["1943-2631"],"issn-type":[{"value":"1943-2631","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[1981,11,1]]},"published":{"date-parts":[[1981,11,1]]}}}
