Have I got this right??

[woolerc01]

If I were to breed a Mojave Royal to a Bumblebee Royal would the possible outcomes be:

Normal
Mojave
Spider
Pastave
Spimo
and I guess they would all be het pastel.
All abuse is welcome if I'm completely wrong, this gene thing aint easy

Sorry, only part right.

Pastel and mojave are codominant mutant genes. Spider is either a dominant or codominant mutant gene; the jury is still out because as far as I know, nobody has proven a homozygous spider royal. In other words, there is no such thing as a het pastel (or het spider or het mojave) that looks normal.

A bumblebee royal has a pastel mutant gene paired with a normal gene and a spider mutant gene paired with a normal gene. A mojave royal has a mojave mutant gene paired with a normal gene. All unspecified genes in both snakes are presumed to be normal genes.

Bumblebee X mojave produces
1/8 normal
1/8 mojave
1/8 spider
1/8 pastel
1/8 mojave spider (spimo???)
1/8 mojave pastel (pastave)
1/8 spider pastel (bumblebee)
1/8 mojave spider pastel (don't know what the trade name is)

By the way, the probabilities are per egg, not per eight-egg clutch.

As above.
Names are mojave spider is a spimo, and a mojave spider pastel is just called a mojave bumblebee. Technically there is such a thing as a het pastel but a pastel being a co dom trait means the het would look pastel and the hom version is a super pastel. But it is not a recessive het pastel that is carried and not shown like het albino is.

Also it a great combo you get a real nice variety, the pastave is a morph I personally like a lot.

Thanks very much, I did think that pastel was like the albino gene. But quite impressed with myself, wasn't too far off.
Thanks again
