The centromeres attach to spindle fibers, which extend from the poles of the cell. One centromere attaches per spindle fiber. Anaphase I: In anaphase I, the homologous chromosomes or tetrads separate.

"WebAbstract. The meiotic prophase I to metaphase I (PI/MI) transition requires chromosome desynapsis and metaphase competence acquisition. However, control of these major meiotic events is poorly understood. Here, we identify an essential role for SKP1, a core subunit of the SKP1–Cullin–F-box (SCF) ubiquitin E3 ligase, in the PI/MI transition. " - Notes of metaphase 1 of meiosis
