Answer:
the proper way to ask the question would be: can a man with diabetes father a child with diabetes, and the answer would be yes there is a 1 in 17 chance if the father has type 1 diabetes and a 1 in 7 chance if the father has type 2 diabetes (diagnosed before the age of 50) and a 1 in 13 chance (if diagnosed after the age of 50) though if both parents have diabetes no matter what type the child has a 50% chance of becoming diabetic
