“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:

He has your eyes.

(someone) has (someone's)(feature)

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.
