Well, first of all, diabetes is divided into 2 types, commonly known as Diabetes Type 1 and Diabetes Type 2.

If you have a Diabetes Type 1, the probability that your child will have the same condition is 1:17. If you are a mother with Diabetes Type 1 and deliver a child when you are under 25 years old, then the probability that your child will be diagnosed with the same condition is 1:25. The probability decreases to 1:100 if you give birth over 25 years old.

The risk that your child will have diabetes is doubled if you are diagnosed with Diabetes Type 1 before you turn 11. Should you and your spouse both have Diabetes Type 1, then the probability that your child also has it will increase starting from 1:10 up to 1:4.

What about Diabetes Type 2? This kind of diabetes does have a larger genetical basis than Diabetes Type 1. Though, a huge influence also comes from external factors such as environments, way of lifes, eating habits, etc.

Generally, if you are diagnosed with a Diabetes Type 2 since you are under 50 years old, then the probability for your child to have the same condition is 1:7. The probability decreases to 1:13 if you are diagnosed with it over 50.
