Let's be honest and address the implicitly given analogy to our modern human world. What are the different motivations males and females have in general and why did she end up in this alpha-position, while still lacking a lot of the advantages a male would have (mating
and procreating with a lot of females)? It's because "the other gender"
also carries all these (particularly very desirable in one gender) traits in them. I always think of men, which have very attractive daughters, like Billy Ray Cyrus (Miley Cyrus) or Rob Schneider (Elle King), but they themselves can't profit that much from the interesting looks (nose) and rather even look like a bum, themselves.
So "the other sex" also inevitably carries around all these (attractive) traits (kind of "reciprocally"), typically: They are there, but don't matter, really. They were inherited and can be passed on, though.
And in this very rare case like this: A female became an alpha. Her masculinity traits, which should rather only exist reciprocally within her (as a female), were coming out so strong, that she beat all the males. Though: No mass-mating (offspring) for her, rather likely: No offspring at all.
