obsolete inviable microcolony, abnormal cell shape, normal cell size (obsolete FYPO:0002226)
OBSOLETE. A cell population phenotype in which a cell undergoes one or a few rounds of cell division before cells die, resulting in the formation a colony that contains only a few inviable cells in which cell shape is altered and cell size remains normal. Up to 6 rounds of cell division (generating 64 cells) may be observed, but 3 divisions or fewer is more typical.
