is your father type 1 or type 2 diabetes? Diabetes does have some genetic tendency to being inherited.
Why do you think you have diabetes? What are your symptoms?
The easiest thing to do may be to borrow your father's meter and testing your own blood sugar.
Fasting blood sugar should be < 95 (ideally in the 80s).
2 hours post eating, should be < 120, but ideally <100.
If you are in doubt go to the dr to get checked. They should test fasting blood sugar and hba1c for a start.
