Strong Family Resemblance/Playing With

Basic Trope: Two related characters, usually a parent and child, look nearly identical.

Straight: Bob looks almost exactly the same as Charlie, his father.
Exaggerated: Bob looks the same as his father Charlie, and his uncle Dan, and grandpa Ed, and great-grandpa Felix when he was younger...
Justified: It turns out that Bob is actually Charlie's clone.
- My Own Grampa.
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 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.
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.
Reconstructed: ???
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!"
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.
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."

Aw, this back button looks just like you!
