i need help understanding this pedigree. i know that its an autosomal inheritance, because the father doesn't infect the daughters and the mother doesnt infect the sons. my confusion is coming from the fact that the disease completely skips the F2 which is leading my confusion. i feel like it cant be autosomal dominant because the disease doesnt appear in all generations, but autosomal recessive. I believe this because the only way it is possible is if one or both parents are carriers to explain this.
