"The parents have three girls."
Translation:La gepatroj havas tri knabinojn.
I understand if they have two or more girls it is knabinojn and if they have three or more boys it is knabojn, is there a separate word if they have a mixed gender group? Or is the masculine form used in that case, such as in Spanish? (hijos - all males or mixed group, hijas - all females)
