'''Basic Trope''': Two related characters, usually a parent and child, look nearly identical.
* '''Straight''':
** Bob looks almost exactly the same as Charlie, his father.
** In a non–parent-child variant, two siblings look very similar.
* '''Exaggerated''':
** Bob looks the same as his father Charlie, and his uncle Dan, and grandpa Ed, and great-grandpa Felix when he was younger...
** The siblings are conjoined twins.
* '''Downplayed''':
** Bob and Charlie share some of their father's features and some of their mother's... but only look alike in the dark or to people with bad eyesight.
** Alternately, Bob looks like his ''uncle'' instead of Charlie himself.
* '''Justified''':
** It turns out that Bob is actually Charlie's clone.
** Bob and his brother are identical twins.
** MyOwnGrampa.
* '''Inverted''': Though not adopted, Bob looks absolutely nothing like anyone in his family.
* '''Subverted''': It seems at first that Bob looks almost the same as Charlie and it's hinted that he must be his son, but it's revealed that [[IdenticalStranger they're unrelated, and the resemblance is coincidental]].
* '''Double Subverted''': Then, Bob's parents inform him that he's actually adopted, and Charlie's his real father.
* '''Parodied''':
** Bob and Charlie look exactly alike except for a height difference, which causes Bob's friends to think Charlie is him and vice versa.
** Bob looks identical to Charlie, despite being adopted.
** Bob looks identical to Charlie. [[DudeLooksLikeALady Charlie is Bob's daughter.]]
* '''Zig Zagged''': ???
* '''Averted''': Bob might somewhat resemble his father Charlie, but the two still look very different.
* '''Enforced''':
** "No, we need viewers to figure out that they're related right away!"
** [[OnlySixFaces The character artist didn't have time to design a new face for Bob, so he shrank down Charlie's]].
* '''Lampshaded''': "Wow, Bob, you're really growing up to resemble your dad, somehow."
* '''Invoked''': Bob idolizes his father Charlie and tries to make himself look as much like him as possible.
* '''Exploited''': Charlie changes his appearance or the appearance of his partner Dana to make it seem that Bob is Charlie & Dana's biological son, to prevent people from suspecting why Bob does not resemble his father or mother.
* '''Defied''': Not wanting to be mistaken for his father, whom he dislikes, Bob dyes his hair and tries to distance his appearance from Charlie as much as possible.
* '''Discussed''': "Aww, Charlie, your new baby's so cute!" "It'd be creepy if he grew up looking just like me, like all those movie children, huh?"
* '''Conversed''': "Dude, this new episode's confusing. Is that Charlie or his kid Bob there? I can't even tell anymore, they look so alike it's just creepy."
* '''Deconstructed''':
** Young Bob loathes his father Charlie, and is constantly burdened by the stress of their strong resemblance, fearing that he will grow up to act just like him.
** A whole society like this ends up having a stagnating gene pool because children are all direct clones of their parents.
* '''Played For Drama''': Bob looks a lot like his late father Charlie, which just serves to daily [[TheLostLenore remind his grieving mother of the loss.]]
* '''Implied''': Bob and Charlie look very alike, but are AmbiguouslyRelated.
