In a genetic paradigm the Y in any chromosome combination always indicates male.  XXYs are considered to be male because of the Y chromosome, yet this is purely a genetic view of reality.  For various reasons lived lives, however, may differ radically from the paradigm.  For example, some XXYs may never virilize (produce secondary sexual characteristics such as a deeper voice, male pattern hair distribution, and enlarged penis) without testosterone being administered.  Again, some XXYs identify as female, or something in between the typical dichotomy of culturally constructed genders.  Gender means the behavioural, cultural, or psychological traits typically associated with one sex.  Gender is a cultural concept and has little scientific basis and certainly should not depend upon a genetic world-view, only.
