Answer 1

Talking about diabetes, it depends on why your grandfather got it, if he has it from genetic factors you’ll be at an higher risk (if your parent got the genetic factors from your grandad and you got them too). If your grandfather developed diabetes from non-genetic factors then you won’t be at an higher risk.

In general it depends on the disease, if it’s caused by hereditary traits then yes, you’ll be at an higher risk, if it’s from non-genetic factors you won’t.
