Paul, while I'm a small breeder, and have produced only a few spider clutches so far, the ratio of spider to normal has been extremely typical--just the same as ratios in lesser and mojave clutches. Sometimes a few more, sometimes less, but usually about the same number of morphs and normals.

I work a lot with the very similar woma mutation, and ratios there are also typical.

This means little, because I know from personal experience how dramatically a single clutch can sway from the average--I got 11 pastels and 2 normals out of a 13 egg clutch from a pastel X normal breeding, once, lol.
