Since each of these independent attributes is graded, it is easy to see the possible combinations and degrees number in the thousands. With regard to gender, we can be in a category of one—ourselves.
Perhaps only individuals who are homogeneously male or female at the highest degree in all five attributes could convincingly describe themselves as only a single gender— the rest of us are a matrix [a mixture].
As for the transgendered, they appear to be uniformly one gender in all three brain dimensions, but of the opposite gender, both physically and genetically.
