some say that the good ol' AS can be hereditary,right?

my silly question is can my father pass down AS to me even although i don't have the B27?

i of course have AS, my sister MAY have AS, and i recall when i was a youngster my father suffered terribly with back pains.AS for him was unDX and he wore corsets and slept on removed doors,i remember his pain and /screams/shouts all too well

Hmmm....did i get my AS from my dear ol' dad?
