The classical example is the ''Drosophila'' w()(speak white-mottled-4) translocation. In this mutation, an inversion on the X chromosome places the ''white'' gene next to pericentric heterochromatin. Normally, the ''white'' gene is expressed in every cell of the adult ''Drosophila'' eye resulting in a red eye phenotype. In the w() mutant the eye color is variegated (red-white mosaic colored) where the ''white'' gene is expressed in some cells in the eyes and not in others. The mutation was described first by Hermann Muller in 1930. ==See also== * Epigenetics * Friedreich's ataxia * Position effect 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Position-effect variegation」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
