i dont believe that, i believe that physical you can adopt genetics but NOT mentally/behavour, its the same with people if your father is a ashole and you been braugt up without ever seen him you wont have his behavour...even sometimes when people are beign braught up with their ashole father then some times they stil NEVER want to be like that....thats also why Pittbulls in our country are never agressive or involved in attack or stuf like you mean, because they only experiance love and normal stuf on the street, not people who are scared and walk with guns and stuf and have their dog tense because they are tense themself, i read on article saying..... "That genetic defense has been a flop however. It turns out that “warrior genes” affect violent behavior only in the small category of individuals who grow up in extremely abusive homes. Children who are raised by loving parents are very unlikely to engage in orgies of uncontrolled aggression"...i think its the same with animals .https://www.psychologytoday.com/us/blog/the-human-beast/201509/what-behaviors-do-we-inherit-genes
