в крови

(у кого)

smb. has it in his blood; it runs in smb.'s blood

С первого же дня [Карабанов] сделался правой рукой Шере. У него была ярко выраженная хлеборобская жилка, он много знал, и многое сидело у него в крови "з дида, з прадида" - степной унаследованный опыт. (А. Макаренко, Педагогическая поэма) — From the very first day he became Sherre's right hand. He had a pronounced agricultural vein, he had acquired a lot of knowledge, and he had instinctive knowledge in his blood, from his fathers and his grandfathers, handed down from their experience of life in the steppe.
