In my family...it appears to have no correlation.
My 4 Grandparents ...3 abstained...1 drank/quit.
My y non drinking parents only 2 children became alcoholics in AA recovery.
Of our 5...2 have addictions.
Both are mine and never saw me drink.
5 Grandchildren...1 is too young...1 in AA... 3 abstain.
My daughter did drink /drug during her 2 older kids early
life. One is in recovery....one abstains....as I mentioned.
When trying to figure genetics...the recessive gene factor
as far as I know...can not be pin pointed.
