I would disagree with this, as evidenced by Loonh (from the Amal'jaa Beast tribe quests) and her mother. There is obviously a special connection she shared with her mother, and it makes sense - whilst they may not take any names, it is most likely that a Miqo'te will depend on their mother to be raised, to learn to hunt, to learn the ways of the clan. The tia in the U tribe are seen helping some women find their roles, yes, but they seem to have basic skills passed down by their sisters and probably their mothers in their early years.
Seeing at they are all about the hunt, I would say that their mothers play quite an important role!
Although the U is not a good example of this, lore wise, the nunh is usually not the clan leader (as stated by Ferne in the lore forums in the Miqo'te naming conventions). Meaning women would have a very important role in the leadership side of the clan, too!

Nunh status does not equate to leadership within a tribe, and in fact, very few nunh ever become leaders.
