Genetic isn't that simple.
1. To have XY (XX) dosn't mean you must develop as a boy (girl). That is controlled by the amount of hormons and the individualy susceptibility to hormons. You could have XX (XY), but develop an outer female (male) gender. And realise in the puberty that you are male (female) in mind. If a child has visable notes of both gender, the parents and doctors decide which gender it become official and "adjust" the gender in an operation. They don't look at the DNA.
2. There are more cases than XY and XX. There are humans with XXX, XXY, XX, XY, only X, and special cases between them.
How would you explain a Hermaphrodite person? There isn't a clear border between male and female.
3. Scientist know for years what is written in the DNA, but know less of how to read it. There are several ways to read one gen, and every time you get another Information. If you read a bit of epigenetics you could learn that the Information of the DNA can be changed without changeing the DNA or the chromosomes. Epigenetics is a very important thing in evolution.
Some animals can change their gender a few times, or the development of their gender is only a result of the temperature.
Thats my scientific biological view.
