Quad Morph Rollover

This calculator is for a specific technique you can use to create quadruple recessive morphs from double recessive morphs, You can also use triple morphs to create quintuples, etc. If you simply use quad hets, the target morph is 1 in 256 and you have to keep a large pool of breeding adults in order to have a realistic chance to hatch your target morph. The rollover allows you to keep a smaller number of snakes without ever needing to face odds worse than 1 in 16.

This allows you to work on more projects, using the same number of snakes that would be required to pursue only one target. It is applicable to any of the recessive corn snake genes. You can also split up the required pairs between different hobbyists/breeders in order to make it a cooperative effort.

To use the calculator, enter the four genes you wish to combine and then click Ok. You can use the full names or any abbreviation or symbols you like, so enter them the way you prefer to read it. Then choose which double morphs you have or that you think you will be able to use. The calculator will then show you which morphs you should breed to each other in order to get to your target. It is advisable to print out your result so that you can look through the various options, and refer back to it later in the course of your breeding project. (Each plan is a complete start-to-finish method to hatch the target morph. You don't need to do all or even more than one of them.) It will take a few times looking through to get a grasp of how it works, so don't be discouraged if it just looks like a jumble at first.

This is not a substitute for understanding mendelian genetics. To use this method you must at least have a grasp of how different crosses work and how to deal with double hets.

Step 1:
Enter Genes or abbreviations. (Use whatever words or symbols you want to read.)




Ok




Step 2:
Check the types that are available to you.
Uncheck the types that are not available.






Note: The original (P) generation can be the listed hets, or the actual double morphs. For example, if it says Hypo het Motley you can use a Hypo het Motley or you can use a Hypo Motley. Using double morphs instead of hets, you can more easily run both halves of a plan.

Note: You can cross the two alternate F2s from the same Plan. For example if you use plan 1 and produce A B het C D from the first set and C D het A B from the other set, you can swap them and breed A B het C D --x-- C D het A B. Swapping produces known hets instead of possible hets. Not swapping produces possible hets, but all of the clutch are at least the same double morph as the parents.
