I think it depends on how you are treated individually by each parent. Personally I get really tired of people saying mothers are the most important. No, they are just a part of it. Fathers are just as critical. In fact, the 'mother', 'father' thing is proven to be false regardless, as there are plenty of gay couples who have children who grow up to be perfectly well rounded, and in most cases, more accepting and kind. So I don't really think the whole mother/father dynamic holds water like people used to think it did.
Now, in my personal experience, I didn't know my mother very well, and we don't quite get along. But me and my dad, heck yeah, good buds! In fact, I recently spent about four hours talking on the phone with him the other night. We never run out of things to talk about and discuss.
My husband, only grew up with his father, a single parent. And he turned out beautifully. Successful, kind, accepting, hard-working, even-tempered and fair minded. He has glorious morals, and I learn from him everyday. So, really... the whole binary parent outlook, is quite outdated. Frankly, it was wrong from the start, people just didn't look into it.
