My dad had some unusual mannarisms mostly involving his hands and arms. I have rarely seen others move their hands and arms in the same way. He died three years ago following a long illness that left him very debilitated for many years.
My daughter is 6 years old and moves her hands and arms in the same way. The resemblence is striking. She didn’t know my dad, having only met him a few times before the age of three. Even then, I don’t think she would have witnessed the movements as he was quite ill and simply didn’t move much those final years.
My brother makes similar movements on occasion but not nearly to the degree my father did. I don’t do this at all, and none of the other siblings do it either. I know I avoid it because it is strange looking.
Do you think movements or mannarisms can be inheritable?
