The Alpha ______

I've pertnear allus seen that blank filled in with Male, the wolf or whatever being assumed from the species of discourse. Even in the case of humans the term has always been Alpha Male. However I have also seen Alpha Female as we slowly have come to discover that some species are matriarchal, e.g., an elephant herd will have an alpha female. In some cases there will be a hierarchy of females even in a patriarchal species and there will be an alpha female in those species. This can get complicated by the tendency of some patriarchal species to have the alpha female get her power from her relationship with the alpha male and in vice versa in some matriarchal species.
