Dialog 1 a chip off the old block [ 親にそっくりな子 ]

Alicia:Thanks for fixing my toilet!
Yukio:No problem!
Alicia:You're really good with your hands. Where did you learn to fix toilets?
Yukio:My dad's a plumber.
Alicia:Oh, I see. You're a chip off the old block, aren't you?
Yukio:I guess I am.

Dialog 2 runs in the family [ 血筋、遺伝 ]

Yukio:That person over there is my Aunt Miyoko.
Alicia:How long has she lived here in the States?
Yukio:Since the '50s. She married my Uncle Ernie, who was an American G.I.
Alicia:Didn't your mom marry a G.I., too?
Yukio:Yeah, she did. So did my cousin Sherry. I guess it runs in the family.
