Is the love for combat sports inherited?

Anonymous
Neither of my two siblings nor parents showed any interest in combat sports. I was the supposedly the only one with that passion. I've been taking both MMA and Judo classes for nearly 5 months now.

Then I just learned recently my great-grandfather was into MMA and Muay Thai. Coincidentally, he was my same age when he started training; 19 years old. Do you some things like the love for combat sports inherited? Like me, he was the only one in the family with that passion towards it.

Even when I've come home with bruises and some cuts, I'm persistent. A couple relatives even said it's like seeing his attitude all over again, as if they were talking to him in female version.
