mrs sweats question right?
There are a few mutations caused by entire chromosome changes. The times the number of chromosome can change can occur when the duplicated chromosomes pull apart and then produce a cell missing a chromosome or having an additional one. For example, XO or XXX or XXY. These are the sex chromosomes where XO means that either the second X is missing, or the Y is missing. Normal would be XX (female) or XY (male). These individuals are able to live with these added or deleted genes. All other missing or additional chromosomes are not compatible with life.

Before they are pulled apart they are called sister chromatids. Once they are pulled apart they are called chromosomes.
Anaphase is the stage of mitosis when chromosomes split apart.
anaphase
To pull chromosomes apart.
Chromosomes will line up in metaphase and in anaphase they will split apart.

Spindles
I belive that they split apart!
mitosis
It is called Anaphase.
