You edit the category page, removing the categories you don't want it to be a subcategory of and adding the ones you do.

For instance, let's say the category hierarchy is Browse>Mothers (or Daughters)>Females. You would remove Mothers and Daughters from Females and add Browse (or in the real case, the actual category you want females to be a child category of. To make Mothers and Daughters a subcategory of Females, you would add Category:Females to the page.
