Bivalents align at metaphase plate stage
WebCells sense tensions and does not progress with anaphase until chromosomes are properly bi orientated physical basis if independent assortment of chromosomes is random orientation of each bivalent along the metaphase plate Bivalents can be randomly assigned along metaphase plate in a variety of ways 4. Anaphase a. WebBivalents or tetrads (four chromatids) align on on the metaphase plate (the equator of the cell) and spindle fibres attach to the kinetichores; protein structures located at the centromeres. In this stage, the nuclear envelope has been fully disintegrated. Anaphase I . Disjunction occurs. This is when the mitotic spindles pull the tetrads apart ...
