“He has your eyes.”
Your friend recently had a baby. She's showing you pictures of him for the first time. You think that the baby mostly looks like his father, but the baby's eyes look like your friend's eyes. You say this.
He has your eyes.
This expression describes someone having a feature (like eyes, nose, chin, etc.) that looks like their parent's. For example:
You have your mother's lips.
Don't you think she has your ears?
You can also use this for personality features that a child shares with a parent:
He has his father's stubbornness.
You usually don't use "___ has your ___" to talk about people who aren't related, even if they do look alike.
