Simchallthetime- I wldnt say VERY high but rather “higher than the general population.”
There’s a lot of conflicting info out there but in general (from the american diabetes association)
if the father has it theres a 1 in 17 chance of kids getting it
if the mother has it- theres a 1 in 25 of kids getting it
If both have it- not sure! i think 1 in 10 but dont quote me
But then again, there’s more to it than genetics and all this is not proven info as far as i know!
Besides of course that hashem runs the world!!!
