abnormal meiotic spindle assembly meiotic spindle self-assembly 2021-09-21T13:31:15Z acentrosomal meiotic spindle assembly A cellular process phenotype in which microtubules self-assemble into a spindle without the participation of the spindle pole body (SPB) during one or both meiotic nuclear divisions. This phenotype is observed in the absence of both bouquet formation and meiotic SPB insertion into the nuclear envelope.
