I snipped a bit, because more or less I feel that the issues you raised there are legitimate, and I've mentioned before that keeping it solely to genotype without any other connotation might actually provide some sort of interesting data, supposing a large scientific study. I still think the poll is silly in and of itself though :3Reasonable Atheist said:
I am by no means an expert in terms of gender issues, but I'll try to answer this one best I can.
To my understanding:
Trans* are umbrella terms that encompass many specific groups/identities, etc.
Transgender specificly means that, in the sex/gender distinction [footnote]http://en.wikipedia.org/wiki/Sex_and_gender_distinction[/footnote] your gender does not align with your sex. Intersexed is a somewhat related condition that, when clinically diagnosed, means that you can not be distinctly identified as male or female[footnote]http://en.wikipedia.org/wiki/Intersex[/footnote]. I specificly mentioned Aneuploidy[footnote]http://en.wikipedia.org/wiki/Aneuploidy[/footnote] because it would cover individuals who do not have xy/xx genotypes. (e.g. XXX, XXY, YYX, etc)
Because, for the most part, we do not have genders that specifically align to non xx/xy genotypes, someone who is intersexed by means of aneuploidy is 'transgender'. (though they may identify with something that they feel align to their genotype, so I can't say this definitively).
