Turner’s Syndrome people have external sex organs approximating a female, and their behaviour is characterized as hyper-feminine, baby care oriented, and showing very poor spatial and math skills. The Turner’s personality, free of all influence from testosterone, tends to be in direct opposition to the typical set of “Tom Boy” traits.
But, none of the above conditions describes the transgendered individual. Transgenderism is far more subtle, involving probably only a few genes on a single chromosome.
