Matching Pairs MeiosisOnline version Match the description of the phases to the diagram of the phases. by Kayla White 1 The duplicated chromosomes move to the centre of the cell. Each centromere attaches to two spindle fibres instead of one. 2 The pairs of replicated chromosomes line up in the centre of the cell. The centromere of each chromatid pair attaches to one spindle fibre. 3 The cytoplasm divides and two new cells form. Each new cell has one duplicated chromosome from each similar pair. 4 4 cells resulting from the replication and division of a single parent cell have half the number of chromosomes. 5 Each chromosome comes near its replicated chromosome pair. Crossing over occurs. 6 The centromere divides. The chromatids seperate and move to opposite ends of the cell. Each chromosome is now an individual chromatid. 7 The duplicated chromosomes and spindle fibers reappear in each new cell. 8 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. 9 The spindle fibres disappear, and a nuclear membrane forms around each set of chromosomes.
