you know, the Y chromosome is actually pretty small and a lot of "male" traits are a result of gene expression on the X chromosome. The only things the Y chromosome is really responsible for are turning genitals inside-out, producing many mini-gnawers & receding hair lines.
HRT demonstrates that MOST of what we consider man/woman from secondary sex traits to behavior, is physiological. yeah xy almost always means one is male (has a Y chromosome and is capable of producing sperm), but in cases of complete androgen insensitivity, people develop as females with normal female genetalia. They are genetically male, but phenotypically female.
