obsolete abnormal cell cycle arrest in mitotic anaphase, with unseparated sister chromatids true absence of chromosome separation, abnormal mitotic anaphase arrest with condensed chromosomes 2013-02-07T12:21:22Z FYPO:0001947 This term was made obsolete because a cell with unseparated sister chromatids is by definition in metaphase. abnormal mitotic cell cycle arrest in anaphase, with unseparated sister chromatids OBSOLETE. A cellular process phenotype in which progression through the mitotic cell cycle is arrested in anaphase under conditions where arrest does not normally occur, and sister chromatids have not separated. The unseparated chromosomes remain condensed. abnormal cell cycle arrest in mitotic anaphase, with unseparated sister chromatids, during vegetative growth midori abnormal cell cycle arrest in mitotic anaphase, with unseparated, condensed chromosomes FYPO:0000620 abnormal cell cycle arrest in mitotic anaphase, with unseparated, condensed sister chromatids
