They had the webbing on the neck removed at birth (and presumably between the fingers). I didn't examine her ovaries, though I'd heard of problems in that are, but I didn't notice anything wrong with her elbows. I'd been told she was XXY, but they definitely mentioned Turner's syndrome. What do you mean by X0? That's what cat breeders use to describe tortiseshells. > Kleinefelter's Syndrome (XXY) causes phenotypical maleness.
