unequal mitotic sister chromatid segregation abnormal mitosis following normal mitosis unequal mitotic sister chromatid segregation following normal mitosis 2015-11-18T15:53:46Z unequal mitotic sister chromatid separation following normal mitosis midori unequal mitotic chromosome segregation following normal mitosis unequal sister chromatid segregation following normal mitosis during mitotic cell cycle A cellular process phenotype in which mitotic sister chromatid segregation fails to separate chromosomes into two equal masses after the cell has undergone a normal mitotic nuclear division and passed through the subsequent mitotic interphase. Unequal mitotic sister chromatid separation may be complete, with two distinct unequal DNA masses located at or near the ends of an elongated mitotic spindle, or incomplete. FYPO:0005069 mitotic chromosome nondisjunction following normal mitosis unequal mitotic sister chromatid segregation during vegetative growth following normal mitosis This phenotype affects the second round of mitosis to take place after a mutation exerts its effect. For example, if a conditional mutant is shifted to restrictive conditions in G1 or S phase and the first mitosis thereafter is normal, but the second is not (even if cells are returned to permissive conditions), this term is applicable.
