abnormal vegetative cell phenotype increased loss of disomic chromosome 3 2020-06-15T13:21:50Z A cell phenotype in which that are aneuploid due to the presence of an extra copy of chromosome 3 lose the extra chromosome, producing haploid daughter cells, at a higher frequency than in otherwise wild-type cells. increased haploidisation in presence of chromosome 3 disomy FYPO:0007392 increased loss of disomic chromosome 3 during vegetative growth This phenotype results from increased chromosome instability in aneuploid cells, restores the cells to euhaploid, and causes haploid colonies to arise at a higher frequency. increased loss of disomic chromosome 3 during mitotic cell cycle midori
