More About Third Gender
Third gender describes a gender identity outside the black and white categories of man and woman. This gender group may include individuals that identify as both male and female or those who have a gender neutral expression. North American culture traditionally acknowledges only male and female as genders, but in other cultures there are third and fourth genders. In India, transgendered individuals are recognized as third gender in terms of legal status.
