CF is a recessive type of disorder which means that both parents must carry the gene in order for the child to inherit the disease. If the child only inherits 1 copy of the affected gene, then the child becomes a carrier. Carriers do not manifests symptoms of the disease but they can pass the disease to their children.
With both parents as carriers, they will have the following chances: 50% carrier children, 25% affected child, and 25% normal child.

Stages of mitosis and what happens in each stage.
Zina [86]
There are 4 stages in Mitosis...
Prophase:
It is the first phase in which the chromatin coil to become chromatids, and those chromatids pair up and the nuclear membrane surrounding them dissolves. The centrioles move to each end (pole) of the cell.
Metaphase:
Where the paired chromatids align in the centre of the cell and spindle fibres attach to them at the centromere. 
Anaphase:
The centrioles act as anchors, tearing the paired chromatids away from each other using the spindle fibres. Each paired chromatid moves to either (the opposite) end of the cell.
Telophase:
Where the chromatids elongate to form chromatin, and a nuclear membrane begins to form around the chromatin at each end of the cell. Cytokinesis occurs in this stage as the cell separates into two daughter cells. In animal cells, there is cleavage as the two cells are starting to separate. In plant cells, a plate begins to form.
