Each new cell has one duplicated chromosome from each similar pair. 2 The spindle fibres disappear, and a nuclear membrane forms around each set of chromosomes. 3 The pairs of replicated chromosomes line up in the centre of the cell. The centromere of each chromatid pair attaches to one spindle fibre. 4 The duplicated chromosomes and spindle fibers reappear in each new cell. 5 Chromatids do not separate. The two pairs of chromatids move away from each other to opposite ends of the cell. Each duplicated chromosome still has two chromatids. 6 Each chromosome comes near its replicated chromosome pair. Crossing over occurs. 7 The duplicated chromosomes move to the centre of the cell. Each centromere attaches to two spindle fibres instead of one. 8 The centromere divides. The chromatids seperate and move to opposite ends of the cell. Each chromosome is now an individual chromatid. 9 4 cells resulting from the replication and division of a single parent cell have half the number of chromosomes.
