Unformatted text preview: of cell 2. Become attached to spindle fibres by centromeres 3. Homologous chromosomes do not associate A naphase • Chromosomes get pulled apart 1. Spindle fibres contract pulling chromatids to the opposite poles of the cell T elophase • Now there are two! 1. Chromosomes uncoil 2. Spindle fibres disintegrate 3. Centrioles replicate 4. Nucleur membrane forms 5. Cell divides Meiosis • 4 daughter cells produced • Each daughter cell has half the chromosomes of the parent • 2 sets of cell division involved...
