Hi,
We all pretty much know what a double helix looks like right? Now this may seem stupid but I'm a graphic artist, and I need visuals.

Question: Does a double helix of the XY sex chromosone look different from the double helix of the XX sex chromosone? What identifies them from each other? How do you knowwhat your looking at?

Personally I haven't seen either, and it was a question that crossed my mind and who do you ask? The experts who have seen both.
