Actually Y chromosomes do have a small recombination region. They pair up with a similarly short corresponding region on the X chromosome. This makes sense because the X and Y chromosomes evolved from a homologous pair, and a part of the recombination machine has been preserved. If one of these crossover events had occurred, the results may have been significantly different.

DUCK. Duck rhymes with truck. If you throw in duck there, you get "stupid dumb duck." +1 Alliteration!
