How do homologous chromosomes pair up
WebEach pair of chromosomes—called a tetrad, or a bivalent—consists of four chromatids.

WebThe homologous pairs orient themselves randomly at the equator. This event is the second mechanism that introduces variation into the gametes or spores. In each cell that undergoes meiosis, the arrangement of the tetrads is different. The number of variations is dependent on the number of chromosomes making up a set.
