sister kinetochore dissociation in meiotic metaphase I, normal chromosome segregation in meiosis I, and sister chromatid non-disjunction in meiosis II
A physical cellular phenotype in which sister kinetochores separate during the first meiotic nuclear division, homologous chromosomes undergo normal reductional division, but sister chromatids divide unequally in meiosis II. Normally sister kinetochores remain together until meiosis II.  Normally sister kinetochores remain together until meiosis II.
