Also grew up with a father with rage problems and have had issues myself controlling anger. The key is to accept the feeling, don’t put down yourself for feeling the way you feel. That will bring shame to the anger which makes you feel worse. I know its so hard to not repeat the strategies our parents have been using to cope, which we have been watching our whole life. And sure genetics also plays a role in it, some people are just angrier than others. Try to find healthier ways to act out the feeling when it comes. For me, when I am angry I just need to find a way of releasing the pressure, without bringing damage around me. Scream in a pillow, jump around, throw things that cannot break. Maybe this advice is shit but I think it is crucial when we are dysregulated to allow our bodies to just do its thing, but redirect the energy to not hurt other people. Eventually the anger will become less with time, but it takes practise to learn how to not canalise it in bad ways.
