Question

anonymous · Answer

On the y-chromosome there is a region called SRY (sex determining region Y). It codes for a protein called TDF (testis determining factor) which induces the development of testis and  thusly other male sexual characteristics.

It's a very good answer, Matthias, but I think the question asked which chromosomes (not which genes) control sex determination. As the two kinds of chromosomes are autosomal chromosomes and sex chromosomes...

.. it is obvious that the sex chromosomes determine the sex of a child (XX = female, XY = male). Sorry, should've read the question more carefully!
