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 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.
