I've had my genome looked at by 23andme for a $100 something dollars. My y chromosome is there with the sry and all. Of the 20 something genes on it, 45% of them are so infinitesimal that they are labeled '"no call". I was wondering if a person with 55% as 'no call' would be passable and so on and so forth within the spectrum. I know there are some professional scientists here, such as Barbie and Deborah who may be able to shed some light.
