The notion that wolves fight amongst each other and the strongest becomes the “alpha” and the weakest is the “omega” and all that, is a misconception that has been debunked ages ago, and even the author of the study who called them “alphas” in the first place is pleading with his old publisher to stop printing the dang book already so this misconception can finally die out.
Wolf packs are more or less just families. One “breeding pair” and their pups, which often stay with their parents way into adulthood.
No idea about personality traits, but there have been studies about what kind of human behavior, especially facial expressions, might be “pre programmed” in our genes. For example, rolling your eyes when you’re frustrated with someone, or raising your eyebrows when you are surprised - that’s something even most blind people do instinctively, despite never having seen it / never learned it from others.
