Combining Genes

All living things are a combination of genes. Some genes affect very minute things, say the thickness of hair, where others determine whether or not you get cancer. Humans have targeted certain genes and selectively bred to make them even better. This applies to sand boas as well. Roy Stockwell selectively bred high orange kenyans for decades before the nuclear line was established. Breeders also combine multiple genes to create stunning animals.The genes are all individual so they can layer over one another and actually combine effects. Lets use an albino stripe as an example. The rufescens of the stripe affects only the pattern of the snake, which does not interfere with the melanin reduction of albinism. The result is an albino snake with a striped pattern. My own little project includes pairing a Nuclear that is heterozygous or het for both albino and anery, aka snow, to a Snow Female that also has blood from a sand boa locality found in the Dodoma Valley of Tanzania. The short version of this would be Nuclear DH Snow x Snow Dodoma Cross. The snow itself is not what is significant about this pairing, it is the combination of the Nuclear and Dodoma blood. The result is a snake known a Nuclear Meltdown. Nuclear Meltdowns have even the orange and contrast of the Nuclears and the sharpness and blushing of the Dodomas. It is a sight to behold. Not only would The snake posses a sort of Nuclear Meltdown coloring, the pairing will potentially produce aneries, albinos and snows. Similar animals have been produced by Brian Russo and should be produced again this coming winter. They are an amazing example of what happens when you understand how certain genes affect others.
