Like father, like son.There is a Japanese proverb like this.
In Japanese, it is said that 'U-ri no tsu-ru ni na-su-bi wa na-ra-nu'.
It means that 'An uncommon child is not born from ordinary parents' and that 'It is impossible to fight over blood'.
And there is another Japanese saying.
'Frog's child is a frog';(Ka-e-ru-no-ko wa ka-e-ru).
