well from what i understand mitosis is just the replication of a cell, a cell divides into two cells and it is not being effected by any other cell so crossing over cant occur

Crossing over occurs in meiosis to create diversity in the genetic material so the offspring is neither identical to father or mother.

in mitosis it does not occur because the parent cell is making an identical copy of itself, so the DNA does not need to vary.
