They null each other out, like matter and anti-matter. You get nothing.

Actually, there is no way to tell exactly what you will get, until the eggs hatch.

Ok, so i guess they would all be normal banded het for the diff. types of stripe then? Thanks

I doubt they would be banded, though some might show some banding.

You would get striped, banded and/or abberrants. Striped and reverse stiped are not simple recessive so there would be no hets.
Striped is a natural morph but it is controled by multiple genes, hence not very predictable. Reverse striped is just a selectively bred abberrant, also controled by multiple genes. They will tend to produce offspring similar but it's not exact like albinos. After many generations of breeding like kinds it gets fairly predictable but throw in another pattern type and that will throw everything off.

No, not that either. The reverse stripe is not a simple recessive trait. Neither is regular striping for that matter. Both traits are genetic, but not simple.

For example, blue eyes in humans is fairly simple recessive in inheritance. But how tall you are is not a simple recessive trait.

You could get very aberrant snakes, some with stripes of one kind or another. Very hard to predict exactly. Just like it will be hard to predict the exact heights of your children before they are born.

Thanks. Then I guess the striped genetics are not the same as in corn snakes. I am just starting to dabble with king snakes now.

Striped in the Cal king is definitely different from striped in the corn snake.

I am not aware of anything better on the subject than Zweifel's paper.
