Technically, isn't it the number of X chromosomes that matters to colorblindness? It's just that people with Y chromosomes almost always have one X chromosome, and people without them almost always have two.

You're correct; we asked for Y chromosomes rather than X chromosomes because it's way easier to have an extra X and not know it than to have a Y and not know it. So if we ask about Y, we can rough-sort into "probably XY" and "probably XX" groups and then look at the statistics for chromosomal deviations within those groups.

... especially if they're responding to xkcd polls.

You have some reason to believe that Klinefelte's syndrome (XXY) is less common among xkcd readers than among the general population?

I thought I did. Now that I've followed your link, I realize that even if it were less common, it would probably only be marginally so, so I withdraw my comment above.
