What does the girl gene mean?

Let me tell you about the genetic differences between men and women. A woman's normal somatic cells have 23 pairs of homologous chromosomes, and the only difference from men is the 23rd homologous chromosome (the other 22 pairs are the same). Women's is XX, and men's is XY, which is the difference between them.
