I have seen some dumb movies in which a kid grows up and looks exactly like his father . I know some twins do that but is there any chance of this happening between a father and his son or somethin ? Even though it has probably never happened (or has it ?) is there a chance it could happen theoraticaly ?

    There is an incredibly, yet none zero chance that all genes passed by one parent may be recessive, while all the other parent’s expressive genes are all dominant and passed on. Theoretically then your scenario is possible.

      There is also an incredibly microscopic, yet non zero chance that a single set of parents could pass on the same exact genes to two separate children conceived at separate times, resulting in 2 genetically identical non-twin siblings.
