Hi there.
Parkinson's and Tourettes syndrome are both movement disorders that can be attributed to a problem with the part of the brain called the basal ganglia (though there are different parts of the basal ganglia that is affected differently by parkinson's and tourettes. Tourette's syndrome can be inherited however it will be very hard to tell if he got it from your lineage. I suggest, for more concrete answers, you may consult with your neurologist or a geneticist.
Hope both of you are doing well with your treatments. Regards and God bless...
