Polycentric chromosome

In genetics, a polycentric chromosome is any chromosome featuring multiple centromeres.^[1] Polycentric chromosomes are produced by chromosomal aberrations such as deletion, duplication, or translocation.^{[citation needed]} Polycentric chromosomes usually result in the death of the cell because polycentric chromosomes may fail to move to opposite poles of spindle fiber during anaphase. As a result, the chromosome is fragmented, which causes the death of the cell. In some algae, such as Spirogyra, polycentric chromosomes appear normally.^[2] They also occur in the sedge, Luzula.^[3]
