In humans at least, it is not the chromosomes, but the presence or abscence of genes for the production of testis-determining factor and mullerian inhibiting factor which determine sex. These genes are normally found on the Y chromosome, but sometimes they are damaged or absent. In which case you get a woman with XY chromosomes. -- SJK
