Consider the following statements with regard to the functions of the centromere in the chromosome.
1. Centromeres are the centres of movement of the chromatids or chromosomes during anaphase separation.
2. Acentric chromosomes lack the capacity to segregate in a regular fashion.
3. Crosing-over in one arm of a metacentric chromosome does not affect the crossing over in the arm of the same chromosome.
Which of the statements given above are correct?

About the functions of the centromere in the chromosome following statements are true.
1. Centromeres are the centers of movement of the chromatids or chromosomes during anaphase separation.
2. Crosing-over in one arm of a metacentric chromosome does not affect the crossing-over in the arm of the same chromosome.
The centromere appears as a constricted region of a chromosome and plays a key role in helping the cell divide up its DNA during division. Specifically, it is the region where the cell's spindle fibers attach.
