Possible Outcomes

A punnet square can be used to predict the outcomes of single gene pairings, but unless you want to get real elaborate with your squaring, a pencil and paper is the best way to discover the outcomes of more complex pairings. You can probably do simple recessive pairings in your head. If you pair a het anery to an albino het anery, you would get aneries 100% het albino, and normals het albino 66% het anery. The 66% ties back to a previous post about possible hets. Lets say you throw a stripe in there though, it gets a little saucier. Make the het anery a stripe het anery, which means, statistically, half your offspring would be stripes, and half would be tigers. Therefore you would have anery stripes 100% het albino, anery tigers 100% het albino, stripe het albinos 66% het anery, and tiger het albinos 66% anery. Heres one thats a little more difficult, lets say you pair a Paradox Snow, to an Albino Splash het anery. Think about that one in your head for a minute... It would be much easier to just write it out, and save you the chance of a mistake. Think about which genes make up each animal. Paradox Snow includes paradox albino and anery, two recessive genes. Albino splash het anery includes albino, splash and anery, even though it is not physically apparent. Which genes are compatible? Only ONE, anery. Paradox Albino and Albino are two completely different genes, and if you don't keep this in mind you could end up with a bunch of normal looking snakes. Since only one recessive trait is compatible, that means that its the only one that can be visually expressed. This leaves three other genes, that were originally visual, to be hets. The possible outcomes for this litter are, anery TH (triple het) albino, splash, albino paradox, and the other is a normal QH (quadruple het) albino, splash, paradox albino, anery. Even though you just paired two extremely high quality snakes, you ended up with a bunch of normals and aneries. This is why you have to be smart with your pairings, think of the outcomes before you throw your male in. You have to strategize and think of the future of your breeding program, or projects you want to work on; being careful can't hurt.
