Recombination

This is a basic question I hesitate to ask but, do the sex chromosomes (X & Y in humans) undergo recombination during meiosis in males?
I can't think of a Y undergoing a cross-over with an X..
Does it take place..?

actually yes. There are regions called something like pseudo-homologous regions, which should (or can) undergo the recombination.

Cis or trans? That's what matters.

Oh. These pseudo-homologous regions must not contain sex-specific genes. Am I right?
